Please find the least area of sheet metal needed to make a water tank.?

A tank is to be made of sheet metal. It is to have a square base and be open at the top. what is the least area of metal that can be used if the tank is to have a volume of 32m^2





please help (with workings) thank you!!Please find the least area of sheet metal needed to make a water tank.?
You can't have a volume of 32m^2. Do you mean 32m^3?





Let l be the length of the sides of the square base of the tank,


h be the height,


and A be the total area of metal used.





Now volume = l * l * h = 32m鲁, so h = 32 / (l * l)


and A = l * l + 4 * (l * h)





Plot a graph of l (= length of base) against A (= total area of metal used) and find the minimum. Or, knowing that the slope of a curve is zero at a minimum or maximum, differentiate A with respect to l, and find a sensible value of l where dA/dl = 0.Please find the least area of sheet metal needed to make a water tank.?
or you can cheat and use excel, and get 48m^2 to be the minimum area. That means base length of 4m and height of 2m

How to calculate sheet metal development size?

i am making a one of the hollow cylinder with using a ss sheet thickness of 2mm. the cylinder inside diameter size is 50mm and outside diameter is 54mm. so how to calculate sheet metal development size and formula. plz help me


thanking uHow to calculate sheet metal development size?
Pie X Dia.= circumference ie 3.14x54=170mm is the width of the sheet reqd.You have not given the length of the cylinder,multiply that length with circumference will give you the area of the reqd.sheet.I do not understand what do u mean by development size.

Is it OK not to use the I/O panel (the thin metal sheet with holes in it) when building a new computer?

I bought a used motherboard and the I/O panel was apparently for a different motherboard. The holes didn't match the motherboard connector jacks (keyboard, mouse, USB ports, sound, etc). I don't see a reason why I can't just skip it, but I might be missing something.Is it OK not to use the I/O panel (the thin metal sheet with holes in it) when building a new computer?
Nope it's not important. Same thing happened to me with a Foxconn mobo.Is it OK not to use the I/O panel (the thin metal sheet with holes in it) when building a new computer?
not really needed.
The panel is pretty much just to keep dust out and sometimes provides info on what each port is for. Unless you'll be using it in a particularly dusty environment, I wouldn't worry about leaving the panel off, as it doesn't ';connect'; to the motherboard or anything. It's just a hunk of metal. :)

Check out the range of paint effects products that Deco-Art makes. You might need to use a 'rust' product, or make your own using vinegar soak if the metal is iron, but there are many different finishes you can get using D-A. And rubbing down after each layer of paint will help.

Which is the most frequently failed ';sheet-metal'; part in the car?

Do you mean rusting through? Front and rear fenders right behind the wheels.





These areas tend to hold moist salty dirt from the road and receive a constant sandblasting from the wheels.





The same for the bottoms of doors and tailgates, the drain holes get clogged and moisture stays in there and works 24/7 rusting the metal.





Rear bumper covers tend to hold dirt and salt in them and rust the metal underneath.Which is the most frequently failed ';sheet-metal'; part in the car?
You'll have to be much more specific as to area and what you mean by a failure. If you're talking about rust floorboards, cab corners, wheel wells, and any other place where gunk sprays up and can't easily get out of.Which is the most frequently failed ';sheet-metal'; part in the car?
i would say the floor board because it gets the most water from your shoes. water on the outside can run off but the floor, it stays there.

Hi i'm looking for sheet metal duct work jobs in montreal canada?

Ha! This is what my husband from South Florida did his whole life in Broward County, married me from Montreal, and we eventually came to Montreal to live. What is most important here, is that you can work legally. I don't know your situation, but once that is established, you need to apply to air conditioning companies. Look for work, meaning all sorts of sites on the web and the yellow pages in Montreal. Call the a/c companies and ask to speak to the boss.

An 800 cubic meter cylindrical container made of sheet metal, including top and bottom is to be designed.?

What dimensions for h(height) and r (radius) will use the least material? Use calculus methodAn 800 cubic meter cylindrical container made of sheet metal, including top and bottom is to be designed.?
The top and bottom each use 蟺 * r^2 of material


The cylindrical portion uses 2 * 蟺 * r * h of material





Together,





A = 2 * 蟺 * r^2 + 2 * 蟺 * r * h of material





Also,





800 = 蟺 * r^2 * h


h = 800 / (蟺 * r^2)





A = 2 * 蟺 * r^2 + 2 * 蟺 * r * 800 / (蟺 * r^2)


A = 2 * 蟺 * r^2 + 1600 / r





Take the first derivative of A:





A' = 4 * 蟺 * r - 1600 / r^2 = 0


0 = 蟺 * r - 400 / r^2


0 = 蟺 * r^3 - 400


400/蟺 = r^3


r = cube root(400/蟺)

How do you determine the surface roughness on sheet metal?

Yes a surface profilometer is one instrument for measuring roughness. It also depends on how rough is rough. If you are dealing with very smooth surfaces (like Si wafers used to make computer chips), you need instruments that are much more sensitive than a typical profilometer. If you are dealing with very rough surfaces for example %26gt;700 microinch Ra roughness, (like very coarse sand paper, 60 or 80 grit), you need a profilometer rated for very rough surfaces.





hope this helpsHow do you determine the surface roughness on sheet metal?
By use of a surface roughness measuring machine or by use of a comparator. The machine can give you values for Ra, Rz etc. The comparator will have several sample surfaces of varying roughness and you have to decide by touch and sight where the surface you are interested in falls.How do you determine the surface roughness on sheet metal?

Can u make a sub box for a car out of sheet metal?

or does a box just have to be wood because the wood conveys the sound betterCan u make a sub box for a car out of sheet metal?
I don't mean to sound like a dick when I say this but they way you asked the question the simple answer is yes. You can do what ever you want if you really want to. Is it advisable? That all depends as well.





The tricky thing about metal is that it produces resonance because it is going to be so thin. Think of those cars that have all those speakers in the trunk and it sounds like they have tin cans rattling in their trunk everytime the bass hits.





You could make a box out of metal but you would need to do everything you could in order to make the box as solid and resonance free (viboration free) as possible.





If you are set on building a metal boxyou need to do whatever you can do dampen the interior of the box to reduce the reflecting frequencies of the bass.





I would highly suggest that you make the box a sealed enclosure.





If they can make boxes out of concrete they can make boxes out of ';pretty much'; anything. As I said before. Every material has a different resonant frequency so the material of the box can play a role in the output of your sub.





If you were to use 1/2'; thick metal and weld all of the pieces together compared to using 1/16'; sheet metal you would be able to tell a major difference.





Honestly, I think it would be more effort that it is worth...


Post up some pictures if you decide to do it anyway....Can u make a sub box for a car out of sheet metal?
Here you go, full on tips and tricks to enclosure construction and other stuff http://spkrbox1.spaces.live.com





The metal will be too heavy and make too much noise.
make it out of wood. if it the look your going for make the box out of wood and put some sheetmetal on the outside.
Make a flat pattern allowing at least one and one half the thickness if the metal for the bends, preferably more.


When you get your pattern done it should allow one to bend


all sides so the the finished produce can be sealed at the corners.


You have to line the interior with foam and egg cartons.


Bass has to be in compression or the speaker blows out.


Also the bass energy need to be reflected of a vertical surface


that can handle the sound energy without vibrating to much.


there should be a 10 to 15 degree angle for reflection of the sound.


Use Gorrilla tape if you cannot afford to have housing welded.
Teh acoustics would be horrible. I would look to cover a wood one made of MDF with sheet metal if you wanted that look.
No to the sheet metal. Use wood or ultra thick plexi-glass. The sound will be alot better.
Yes you can!!! BUT- it will take proper tools,and you will need to protect the contacts from hitting the metal. The box will work, but will produce a hollow, tinny effect (not good) A way around this is to line the metal with carpet or rubber,or even fiberglass insulation......


It sounds easier and simpler to use wood, but I think outside the box too!!! You can make it work, and besides--how many ppl can claim they have a meal sub enclosure???





ALSO--USE RUBBER WASHERS AT SCREWHOLES TO DAMPEN THE SHOCK BETWEEN THE FRONT SIDE OF THE SPEAKER AND THE CONTACT POINTS ON THE METAL





Good luck to ya!!!

Which wrangler has a strongest or thicker sheet metal panels 1995 YJ or 2003 TJ?

Almost all sheet metal in US built cars since the eighties start out as 18 ga. metal that is stamped into the shapes needed. Some parts use thicker gauge steel depending on the strength needed in the part. This of course stretches the steel and you may end up with 22 or 24 ga. metal in places, especially where large curving shapes are stamped to fit the profiles of some cars' fenders. I've researched this myself and the info is pretty sparse on the net, but after talking to a few body shop people, this is the best answer i've found, although it applies to all US and foreign made cars and trucks.

A 6'; x 6'; square sheet of metal is made into an open box by cutting out a square at each corner and then...?

folding up at the four sides. Determine the maximum Volume, Vmax, of the box. Can you please help me with this i know it has to do with optimization.A 6'; x 6'; square sheet of metal is made into an open box by cutting out a square at each corner and then...?
Finding the derivative of a function, say f(x), leads to finding the slope of the tangent line at x. If the slope is 0, then you have the possibility of a minimum or a maximum at x.





So, you need to find an equation for the volume of the box, take the


derivative, set it equalt to zero, solve for x, then use the second derivative (or a simple graph) to tell if the value you get is a minimum or maximum, or simply an inflection point.





If you draw a square with a notch of sixe x removed fom each corner, you will see that what is left of each side is just 6 - 2x. Stare at the picture for a moment, and it will become obvious to you that the volume of the box is the area of the base, which is (6 - 2x) on a side, times the height of the walls, which is just x.





So, the volume of the box is simply





volume = height times area of base





v = x(6 - 2x)^2





v = 36x - 24x^2 + 4x^3





Find v' then solve for v' = 0, draw a graph of v' to convince your self that at least one of your solutions is a max, and you are done.





HTH





CharlesA 6'; x 6'; square sheet of metal is made into an open box by cutting out a square at each corner and then...?
Basically you need to make a mathematical expression (function) for the volume in terms of x (the cutout size). Then take first derivative and then set this equal to zero, then simply solve for x.

Drawing an altitude from a vertex gives you a height of 10sin@ and the longer side of the trapezoid 10cos@ +10 +10cos@ = 20 cos@ +10.


The median of the trapezoid is 10 +10cos@


Area is 10sin@(10 + 10 cos@) =100sin@ +100sin@cos@=


100sin@ +50sin2@

Yes it could, heated metals have less resistance to sheering forces (tearing) the trouble is it would soon heat up too. in which case it'd probably coalesce (squidge together).

Would this theory be considered to heavy for it to work?Is there any possible way that a I could design a sheet of space craft metal using only titanium and ceramics?
Why the ceramics? That only makes sense if there is a lot of heat to dissipate. Think about how you might control for torsion due to uneven heat transfer and how you might bond the titanium layers.





If you are only hanging about in space, then good old mylar foil would likely do but if it is to pass through an atmosphere, then you need to take account of all the factors, loads and temperatures likely to be encountered.Is there any possible way that a I could design a sheet of space craft metal using only titanium and ceramics?
You don't say what you are designing it to do. Titanium isn't a good material to use at high temperatures, it is too reactive. Titanium burns just like magesium, once the temperature gets high enough.

Hammer to shape, File to fit, Paint to match.
The easiest way, if you've never done it before, is to pay someone else to do it for you.
It can be done, but you had better be a good welder and you will probably want to round out the halves of the tank on an english wheel before you weld it. Watch Orange County Chopper and similar shows. I think it would be easier,cheaper and better to buy a new one or to search around a motorcycle wrecking yard for something suitable.

Stress analysis is used to determine whether the expected loads are within the bracket's strength, and by what factor. This can be done through hand calculations (plugging numbers into formulas), or by finite element analysis.

What is the gauge number of sheet metal?

Just a measure of the thickness, when you get pretty small, there is not a decimal equivalent.





There is a difference between wire gauge and sheet metal gauge.What is the gauge number of sheet metal?
it comes in differnt gauges 14 16 18 .........depends on the app.common 14 or 16What is the gauge number of sheet metal?
http://www.onlineconversion.com/gauge_sh鈥?/a>





http://www.engineersedge.com/gauge.htm
Gauge of sheet metal refers to the thickness of the metal. the larger the no. the smaller thinner the thickness. sheet metal comes in many different sizes. 26 GA. is about the smallest Ga. that is used. ';light residential'; , 16 Ga. for heavy commercial, 8 Ga. for industrial. Than we have aluminum, It is measured in decimal points. The smaller the no. the thicker the sheets. Stainless steal is the just like aluminum.


I sure hope that answers your question.

Were can i find some sheet metal?

I need some sheet metal not too thick and not too slim thick enough for me to bend into shapes easy maybe there's a store you know or something I could just use im working on something.Were can i find some sheet metal?
Hardware stores, sheet metal fab shops, on line.


http://www.onlinemetals.com/Were can i find some sheet metal?
Most hobby, craft, and hardware stores carry modest sized brass, copper, and aluminum sheet from K%26amp;S Engineering.and most home centers and hardware stores carry larger sheets of aluminum and steel, often from Steelworks, as well as carrying longer narrow strips (up to 12'; wide) of aluminum and galvanized steel flashing. For bigger sheets and cut to size, look up Sheet Metal Shops in the reference pages - they mostly work in 22-26 gauge that is used for ducting, etc.
My dad always told me that if you need things done right, find a mexican. I'm pretty sure that since your using the internet and yahoo you are far from being a mexican, with that said I think you should drive down to your local Home Depo and find the cutest mexican and have them help you out.

What is the shearing angle of punch for sheet metal shearing?

the geometry of shearing punch designWhat is the shearing angle of punch for sheet metal shearing?
Typically, the punch and die hole diameters are chosen so that the clearance between the 2 is 1/3 the thickness of the sheet metal. (A little more for more brittle materials and a little less for more malleable ones.)





The inverse tangent of 1/3 is 18.43 degrees.What is the shearing angle of punch for sheet metal shearing?
shearing angle of the punch is the method to reduce the load on the punch without reducing the capacity of the punch to shear a given thickness of material.normally the punch face is parallel to the surface of the die,in shearing angle punch face is at an angle which reduces the forces acting on the face of the punch.
I would like to see the correct answer on this.
15 to 20 degree will work better

How are the two pieces of sheet metal shown at the below url held together?

How are the two pieces of sheet metal shown at the below url held together? There are just three ';dents'; holding them. Does this type of connection have a name? What is the name of the tool that makes it / how do I make it?





http://home-and-garden.webshots.com/albu鈥?/a>How are the two pieces of sheet metal shown at the below url held together?
This is a older form used to hold metal together by stamping them together. This is not spot welding and there is not rivets involved, rather a punch is applied and pressed into the two metals creating the seal. Can not be done by hand.





Hope this helps.How are the two pieces of sheet metal shown at the below url held together?
They look like pop-rivets (the kind of rivet that can be attached without access to both sides of the rivet). You drill a hole, insert the pop rivet through and then squeeze the tool to pull and snap off the interior part.
I believe it's made with a dimpler.


The operation is similar to a hole punch but with different dies.


There are hundreds of variations of this tool with both hand held and large commercial types available.
It is called spot welding. The pieces are held in a clamp, while high current is passed through the pieces causing the metal to melt together. It is how cars are built.
to me they look like rivets , but not the cheesy kind we use at home in our pop rivet guns
THOSE LAST TWO PHOTOS LOOK LIKE THE METAL IS COPPER SHEET AND IF THEY ARE THEY ARE NOT SPOT WELDED TOGETHER. NEED BETTER FOCUS TO SEE THE METHOD BETTER.
Those ARE spot welds. They look raised but are infact not, just a different color from the weld. You cant simply dent metal and make them stick together, especiall in the applications shown. If anyone noticed, the ';spots'; in question are not at the corners or bends in the metal but where one piece of metal lies flat over another. They ARE spot welds.
That is not spot welding! Those are pop rivets. They are easy to install aluminum rivets that use a tool to expand them once they are installed. Check out this site.





http://www.emhart.com/products/pop/rivet鈥?/a>
The raised areas on those pictures do not look like spot welding......instead , they appear to be solid aluminum rivets.


The small indication of a dot in the center if the rivets means that they are a hardened alloy. In a few of the pictures there is a consistent countersunk depression indicating that the holes were dimpled prior to squeezing , or bucking the rivets. This process is used in the assembly of aircraft. The pictures do not indicate spot welding, because the quality of the pictures would not detail the small surface disruptions of spot welding.


Spot welding leaves Flash and Spalling, the burnt areas consistent with a weld, and these pictures do not have that.


And, spot welding does not raise the surface of the metal, it actually causes shrinkage after cooling. Aircraft Tool Supply and Brown Tool sell rivet squeezes and everything you need to make joints like that. Any questions feel free to email me.





Ok ok Here is a spot weld http://www.physics.ohio-state.edu/~herma鈥?/a>





And HERE is a rivet Joint http://www.our-rv7a.com/wings/wings04240鈥?/a> fifth picture down





http://brian76.mystarband.net/FuselageJu鈥?/a>





Now? Does It still look like a spot weld?





*****NOTICE I SAID THAT THEY ARE SOLID RIVETS*****


SOLID RIVETS ARE NOT YOUR HARDWARE STORE TYPE RIVETS, AND THERE IS NO HOLE IN A SOLID RIVET, AS THE NAME IMPLIES, BUT THERE IS A DOT TO INDICATE THE GRADE OF RIVET.








SO YOU POSTED THE PICTURES?


TAKE SOME THAT ARE BETTER FOCUSED AND REPOST
It's called spot welding. It's commonly used to hold sheet metal together, like in automobiles.
I believe those '; dents '; are spot welds, done by a spot welder. which typically consists of two long finger like electrodes which clamp down together [finger tip, to finger tip] on two pieces of sheet metal then heated hot enough to weld them together.
it is done using an industrial pneumatic stamping press unless you are a millionaire. you cant afford it

Lincoln makes a nice unit and it's easy to get parts anywhere. Also check out Miller equipment. I was a production welder for many years and we used Miller equipment in the shop.What brand home welder should I buy for welding sheet metal and angle iron?
Personally, I prefer Miller brand....have had problems in the shop with other brands more often than with with Miller.


http://www.millerwelds.com/products/


Check the welding message boards for info too..
sheet metal is a thinner metal than angle iron,and any welder and the proper rod will work just fine,but thin metal ,you need a cetylene and oxygen bottle system.. it will do you a better job. unless you are a so so fine welder that can take a 6011 rod and make it not burn through this thin stuff.. the welding field is technical nowa days.and the lincoln is the proven welder of the four..

I want to fix holes in my car by welding sheet metal to it... what grade sheet metal would i use?

I NEED TO ORDER THIS CERTAIN MATERIAL SPECIFICALLY TO MANUFACTURE PARTS FOR A CAR. I NEED TO KNOW THE FULL MATERIAL NAME, CARBON CONTENT, ETC.I want to fix holes in my car by welding sheet metal to it... what grade sheet metal would i use?
1020 Low-Carbon Cold Rolled (CR), Pickled %26amp; Oiled. That's a fine steel for making your own body panels.





But, be advised that many a newer car (mid-eighties on) use thinner body panels made from a Higher Carbon steel. I believe this was to save material, and weight, and help gas mileage.





Such steels should not be welded with a gas torch, because of all the extra heat it creates. Also, depending on the area you're trying to fix, you could be replacing a load-bearing section with a low-carbon steel repair, which can weaken the structure. Even the heat from a MIG weld can mess with the grain structure, and cause cracks if it's a high-stress area. There are some parts that manufacturers INSIST you replace, rather than weld, for these very same metalurgical reasons.





You might be able to get a higher carbon steel sheet (harder to get than you'd think), but it will either be annealed when you get it, which makes it no better in terms of strength, or you will need to harden %26amp; temper it, which would be all but impossible unless you have the knowledge and equipment.





I believe the Factory Shop Manual will have such instructions. Unless your repair is to an old car, or just a very small fix, you may want to play it safe and check first.





If your car is an older model, you can go to town with the Mild Steel sheet. 16 guage is heavy, and forgiving of much shaping and sanding, but it is harder to work. 18 Gauge is probably the lowest I would go for a car panel...if it were not too big. Also, if you choose the galvanized route, be sure to remove all of the plating in the area you are going to weld. Not only are zinc fumes poisonous, the zinc will mess up a sheet metal weld in no time flat.





Good Luck, and be safe.I want to fix holes in my car by welding sheet metal to it... what grade sheet metal would i use?
!st it's not galvanized. 2nd the gauge or thickness can vary dependant on the year model of the car. I would suggest checking with US body and other suppliers to see if they offer a patch panel for the area of concern. if not perhaps changing the entire panel would be better depending on the location of the hole. if you are intent on making you own patch I would go to a salvage yard and buy a used hood or trunk lid that had some damage but still enough good metal for the size patch you need and make it out of that.
find a donor sheet metal car in a junk yard cut the panels you need and braze them to your car panels as fillers..
ummm why dont you go to a junk yard and see if they have an extra doorto your car in your color and replace the door, or a door of your color car and cut out a piece of it and put it on your holes it could work
Its just plain 16Ga Galvanized Iron Sheet metal.

For industrial roofing metal sheets, is galvalume better than galvanised sheet?

Galvalume lasts far longer than galvanized in almost every condition.





Galvanized is a zinc coating, while Galvalume is a zinc-aluminum coating. The aluminum in this mixture makes the panels more corrosion resistant than galvanized.

A manufacturer cuts squares from the corners of a rectangular piece of sheet metal that measures 5 centimeters by 3 centimeters. The manufacturer then folds the metal upward to make an open-topped box. Letting x represent the side-lengths (in centimeters) of the squares, find the value of that maximizes the volume enclosed by this box. Then give the maximum volume. Round your responses to two decimal places.A manufacturer cuts squares from the corners of a rectangular piece of sheet metal that measures...?
the dimention of the base of the box:

A piece of sheet metal is rectangular, 5ft wide 8ft long. Congurent squares are to be cut from its 4 corners.?

The resulting piece of metal is to be folded and welded to form an open-topped box. How should this be done to get a box of the largest possible volume?A piece of sheet metal is rectangular, 5ft wide 8ft long. Congurent squares are to be cut from its 4 corners.?
Let four a ft x a ft squares be cut from the 4 corners


Dimensions of the open top box are (8 - 2a) ft x (5 - 2a) ft x a ft


We must have 0 %26lt; 2a %26lt; 5 (thus 0 %26lt; 2a %26lt; 8 also) (i. e.) 0 %26lt; a %26lt; 5/2


Measure of its volume V = 4a^3 -26 a^2 + 40a


dV / da = 12 a^2 - 52 a + 40 = 4 ( 3 a^2 - 13 a + 10) = 4 ( a - 1) ( 3a - 10)


a %26lt; 5/2 implies we cannot have 3a - 10 =0


So dV/da vanishes when a = 1.


Now d^2y / da^2 = 24 a - 52 which is negative at a = 1


Hence V is maximum when a = 1 and


max V = 6 x 3 x 1 = 18 c. ft.

How can we check the gauge of a sheet (metal sheet) ? Whats the max. gauge and whats the min. gauge of the?

How can we check the gauge of a sheet (metal sheet) ? Whats the max. gauge and whats the min. gauge of the metal sheets ? Which is better ?How can we check the gauge of a sheet (metal sheet) ? Whats the max. gauge and whats the min. gauge of the?
There ae so many instrument can be use for thickness tester.


Please choose it one, by Elcometer, Mitutoyo, EtcHow can we check the gauge of a sheet (metal sheet) ? Whats the max. gauge and whats the min. gauge of the?
Gauge can be checked by micrometer. The gauges are from 7/0 up to 35 in India. The larger the gauge lesser is the thickness except those specified as x/y. eg.


Gauge = Thickness mm


7/0 gauge= 12.70 mm


6/0 gauge = 11.79mm


0 gauge= 8.23 mm


1 = 7.62


2 = 7.01


14 = 2.03


35 = 0.21


I think you misunderstood what the gauge is. The gauge of a sheet or wire denotes the thickness or diameter of it; a sheet metal of some gauge will have thickness same as the diameter of the same gauge. So there is no better or worse gauge.


If you are asking grade, well then it will depend upon the application.
I don't know what you think gauge is.





It is a measure of the thickness of the metal, and can be measured by various methods like a micrometer.





It can be as thin as 0.001 inch or as thick as 1 inch.





.
Just use a SWG ( Standard Wire Guage ) or BWG ( Birmingham Wire Guage ) tool.


They just have slots in them with the guage stamped next to the slot.


Every sheet metal worker will have one.





Or if you know what measurement relates to which guage, use either a micrometer or vernier to measure the thickness and then look up what that relates to in Guage.





Best guage to use depends on the application.
you can use micrometre or vernior caliper.
a ruler will work 1/6 =12 g 3/16 =7 g 1 /32 = 14 g if you want any thing thicker or thinner s.w.g. i work with steel so i just can tell from looking but it takes practice a S.W.G. is the right tool ( standard wire Gage )

When you fold up the sides, the height is going to be 6 inches. If the volume is going to be 294, we can divide by the height to get the length times width.


294/6=49


Each remaining side is 7 inches


Each original side is 6 inches (cut away) plus 7 inches (left behind) plus 6 inches (cut away), or 19 inches





_/An open box is to be constructed from a square piece of sheet metal by removing a square of side 6 inches from?

Considering the Anti-Union sentiment I've seen on Answers, you're really brave posting this question!





My perspective is with short-term contract work. This current job is going to run a year, which is the longest hubby has had in 7 years! Normally, we end up with about 7-10 W2s in a year.





Benefits to being in a Craft Union:


-You can switch companies without loosing your pension and health care (if yours is like the IBB where the union holds %26amp; administers the plans and the companies just pay in during the term of employment)


-Continued training. I've lost track of how many certifications and hours of training the IBB does every year.


-Pay scale. As you've noticed, Union jobs pay more.


-Representation. If there's a problem, you're not alone in facing the big company. You have the right to have the Steward (Union Rep) with you during major discussions with company people.


-Safety Standards. Unions are usually very strict about OSHA standards for both workers %26amp; the company.





Talk to your Steward or the Hall, they can give you more information than the people on Answers.





From what I've noticed, a lot of the Anti-Union people are ignorant of the difference between Industry Unions (Teachers, Airline Pilots, etc) and Craft Unions (Boilermakers, Pipefitters, Ironworkers, etc). Full Referral Unions are a foreign concept to most people. Or, they think unions are irrelevant, antiquated relics of the past.Ive recently joined the sheet metal workers union,what are the benefits of having a union job?
How about job security? Have you ever had a job with a rotten boss that you feared?? With Union leadership, you can work to make it a better working environment...





How about benefits? Most union jobs have medical, dental, retirement and 401-k benefits. If your job has a 401-k, USE IT!!! You will be amazed how quickly you can build up your money, and at the very least if they have a match, contribute at least as much as they match!! It's as close to free money as you will ever get!





Most people that are against unions have probably had a bad experience with a job that the boss threatened them if they went union. Or, they are unskilled workers, unlike yourself!





This administration is trying to eliminate unions and high paying jobs, thus in Bush's first six years you never heard a word about illegal immigration. They WANT the cheap, unskilled labor from Mexico. Profits are WAY UP at corporations, thanks in no small part to illegal immigration!

You have a piece of sheet metal. Your task is to use this material to create a container with a maximum volume?

a) which shape would have the greatest volume: a squared based prism or a cylinder?





b) Justify you answer using a fixed surface area of 3500cm squaresYou have a piece of sheet metal. Your task is to use this material to create a container with a maximum volume?
This one is tricky, its actually easier to do b that a, so i will show you b. Then i will show a without substituting a value





Firstly given a surface area A


Prism:


1 square surface = A/6


one side = 鈭?A/6)





Volume = side^3 = [鈭?A/6)]^3 = (A/6)^(3/2)





If Suface Area = 3500cm^2


Volume = (3500/6)^(3/2) = 14 088.8385cm^3


______________________________________鈥?br>

Cylinder:


A = 2蟺r^2 + 2蟺rh





Now A is set, but r and h depend on each other, we need an equation for h in terms of r





A = 2蟺r^2 + 2蟺rh





A - 2蟺r^2 = 2蟺rh





h = (A - 2蟺r^2)/2蟺r





now


Volume = 蟺r^2h


eliminate h by substituting the equation for h





Volume = 蟺r^2(A - 2蟺r^2)/2蟺r





simplify/expand





Volume = (Ar - 2蟺r^3)/2





Now we need to find what radius will maximise are Volume


we need to find the derivative V '





V = (Ar - 2蟺r^3)/2





V ' = ( A - 6蟺r^2)/2





Max/Min when V ' = 0





( A - 6蟺r^2)/2 = 0





A = 6蟺r^2





r = 鈭?A/6蟺)





But is it a max or a min, find V ' ' to find out id V ' '(鈭?A/6蟺)) %26lt; 0 its a max





V ' '= -12蟺r/2





V ' '(鈭?A/6蟺)) = -12蟺(鈭?A/6蟺)) /2 %26lt; 0 therefore max volume when r = (鈭?A/6蟺))





So max volume


r = r = (鈭?A/6蟺))


V = (Ar - 2蟺r^3)/2





V = (A鈭?A/6蟺) - 2蟺(鈭?A/6蟺)^3)/2





When A = 3500





V = (3500鈭?3500/6蟺) - 2蟺(鈭?3500/6蟺)^3)/2 = 15897.55186 cm^3





So the cylinder has a greater Volume


______________________________________鈥?br>

EDIT:





Now part a) Compare without substituting 3500cm


V(Prism) = (A/6)^(3/2) = (A/6)^(1.5)





V(Cylinder) = (A(A/6蟺)^0.5 - 2蟺(A/6蟺)^(1.5) )/2





Comparing these two is too difficult we need to simplify





V(Cylinder) = (A(A/6蟺)^0.5 - 2蟺(A/6蟺)^(1.5) )/2





V(Cylinder) = ( A^1.5 (6蟺)^-0.5 - 2蟺 (6蟺)^-1.5 A^(1.5) )/2





V(Cylinder) = A^1.5 [ (6蟺)^-0.5 - 2蟺 (6蟺)^-1.5 ]/2





V(Cylinder) = A^1.5 x (0.076776)


(correct to 6 decimal places)





V(Prism) = (A/6)^(1.5) = A^1.5 (0.068041)


(correct to 6 decimal places)





And from here you can see V(Prism) %26lt; V(Cylinder)

Is there any paint that is resistant to battery acid, so that sheet metal will not rust, recommendation ?

Battery acid spilled in the trunk , and attacked paint some rust has begun .Is there any paint that is resistant to battery acid, so that sheet metal will not rust, recommendation ?
I know of no paint that is resistant to battery acid.


We're talking about SULFURIC ACID here folks.Given


time, it'll eat thru 10'; of homogenous steel.


There are ways to neutrolize this acid,such as a


simple thing called bicarbonate of soda.Can be had


at any grocery store.


Get a big box of the stuff,really cheap,lay a good


layer of it down in your trunk,use a spray bottle of


water to wet it down.

Square steel tubing and sheet metal?

I live in south Jersey, i was wondering if there are any places where i can purchase steel products.Square steel tubing and sheet metal?
Home Depot has square steel tubing.Square steel tubing and sheet metal?
Most hardware stores these days (in US) carry a modest assortment of square tubing under the brand Steelworks. More and more steel retail stores are opening which will cut to size and charge about 20% more than whole lengths - Metal Supercenter - look under steel or metals in Yellow pages. And many ';surplus'; steel centers also sell full 20 or 24 foot lengths of new tubing they keep under shelter.

Manufacturing question: Is there a difference in sheet metal bend allowances between v-forms and wipe forms?

Are there seperate formulas for calculating the two different bending types?Manufacturing question: Is there a difference in sheet metal bend allowances between v-forms and wipe forms?
I wish I could say for sure. But I am only familiar with the V forms. My experience is that there are only two main factors. Number 1 is the material itself. The material bends around its neutral axis which is not necessarily the center of the material. For Stainless steels it is about 45% of the thickness measured from the inside of the bend. For Carbon steel about 33% and for Aluminum 25%.





The other factor is the inside radius of the bend. For Sheet metal the inside radius is usually about 1 metal thickness for plates thicker than 3/16'; the inside radius is usually increased to 1 1/2 x the thickness or more.





We use the wipe type forms for the thinnest materials. The thinner the material the less errors in estimating the bend allowance will effect the final dimensions.Manufacturing question: Is there a difference in sheet metal bend allowances between v-forms and wipe forms?
In mild steel if you are still ';air'; bending it, no. The width of the bottom die can have a significant effect on the amount of material stretch in forming, so conversely, the gap between the wiper and the die block also needs to be considered. It's not unusual in mild steel fabrication to actually coin the material while forming if a bottom die opening is less than 6T. Even with the variance in thickness, tensile strength and grain direction in mild steel fabrication, as long as your measurements are being done with a tape measure, bend allowance calculations will generally be close enough.,

Ford and chevy sheet metal vs. japanese cars?

ok i test drove an 2008 mustang today and i have to admit i think that american cars feel more solid. The salesman told me that ford uses more sheet metal or whatever thats why it feels solid. Im just wondering, does Chevy do this too? And how come japanese cars build theres lighter? are there any japanese cars out there that feel soild like ford? i think im gonna switch to american made, just for the solid feelFord and chevy sheet metal vs. japanese cars?
Chevy is my fav, my work truck just hit 233559 last night.. and our other ford is over 200000 as well, purrr like kittens.. i am a chevy guy as well, but USA built is USA built... Maintenance is the key. most cars are a combination of fiberglass and metal, they have been like that for years. Suspension will also make for a solid feeling while driving.Ford and chevy sheet metal vs. japanese cars?
truth -





so, which is better? the Ford designed by americans and built by mexicans, or the Honda designed by asians and built by americans?








the reason american cars ';feel'; more solid is because they are made out of heavier parts...to make them ';feel'; better.





this better 'feeling' results in lower fuel mileage, and honestly does not help the resale or build quality of the cars, as is obvious by their rankings on JD powers and consumer reports lists...






Thank you. Good for you. I drive a Chrysler 300C and that is a great car. The US cars are really good now, and the Japanese cars are made like tin cans. Do you know there is no such car as Lexus? Nope. Toyota that is toe yo tah, just slapped that name on various models such as Aristo and a few others. When you buy a Lexus you are buying a glorified Toyopet. That is the original name for Toyota cars and were originally built on truck chassis. Stick with the US cars and you will not go wrong and at the same time you are helping our economy. If one buys a Japanese car, that car is dumped in the US; the same car cost at least 30% or more in Japan.
If you want a nice solid car, get yourself a Ford, GM, or Chrysler. I'm a Ford guy, but I wouldn't have a problem driving a GM, or a Chrysler.





And congratulations on switching to American made cars. They're built to last, and to withstand the conditions in this country.





And don't listen to what the honda enthusiasts say, they're just jealous.
I think American cars are really built to last and much stronger and ';solid'; compared to japan cars, that's true and that's why they costs too much. Japanese cars have simple specs and features that's why you need to add parts you can see from carpartswholesale.com to make it more effective and good.
American cars for the win! Especially Chevy, Dodge, and Ford. My 4 favorite cars: 2009 Dodge Challenger, 2009 Chevrolet Camaro, Pontiac Solstice, and a 2009 Chevrolet Corvette.
American cars have the solid feel but hinders the cornering abilities. Japanese cars feel light to keep the power to weight ratio balanced. Japanese cars are can definitely corner better and faster than American cars by far.
Japanese cars are lighter so they can handle better, go faster, accelerate quicker, and get better gas mileage.

Can galvanized sheet metal partially buried generate electricity?

The skirting around my house, with about 12'; in the ground was found to be transmitting enough electricity to be arcing at joints that did not have a good contact.Can galvanized sheet metal partially buried generate electricity?
The voltage and power generated by zinc in ground would be too low to make a good arc. You probably have a poor earth connection in your house wiring and the stray current through the ground is causing that spark.





Put a voltmeter across the gap. You'll probably find that the current is AC while a zinc cell would give DC.Can galvanized sheet metal partially buried generate electricity?
Sun spots can cause DC electric currents to flow through the ground in one direction and your galvanized skirting could 'complete' a circuit. Therefore there may be more than one cause for what you observe. A battery cell may consist of two different metal strips suspended within an acid, however, two similar strips suspended within acids of different concentrations at each strip might cause a current. If your metal skirt becomes part of the ground path for your house electrical system it might transmit electricity. Try to measure the DC voltage across the arcing gap which may eliminate certain possible causes and point to the skirt acting as a weak battery cell. Any current from sun spots would vary and perhaps disappear with time.
The voltage that you get this way will be very small, not sufficient to cause an arcing. Further, the zinc plating on the galvanized metal is thin, in order of microns, so it can not even generate high currents. There is no inductance present in this circuit.


To sum up, there is nothing which can cause arcing as a result of galvanization, in reference to the case you are telling.





There may be stray voltages like - induction from an over head transmission line, poor grounding of household wiring, long pipe line touching the metal sheet the pipe lines not grounded properly - You may be standing on a perfectly insulated pair of shoes and it is the spark of static electricity discharge from your body to the fence. Except the last case, all other are most likely ac sources.





I would suggest you to investigate this as this voltage may cause unpleasent shock to an accident.

It will fold like a trapezoid with bottom = 10 cm


Height = 10 sin 螛


Top of the trapezoid = 10 cos 螛 + 10 + 10 cos 螛

Area = (1/2)h(top + bottom)


A = (1/2)(10 sin 螛)(10 + 20 cos 螛 + 10)


A = 5 sin螛 (20 + 20 cos 螛)


A = 100 sin螛(1+cos螛)


A' = 100(cos螛)(1+cos螛) + 100(sin螛)(-sin螛)

100(sin虏螛) = 100(cos螛+cos虏螛)


1-cos虏螛 = cos螛+cos虏螛

Does anyone know who sells .023 flux cored wire? i have a gasless welder and am welding some sheet metal.?

Welding tipsDoes anyone know who sells .023 flux cored wire? i have a gasless welder and am welding some sheet metal.?
.030'; flux cored wire will work if you get .030'; tip to accommodate the wire. Otherwise, the larger wire will jam up in the tip. It will take a little more power to run it and if you haven't already done it you might have to change the taps in the welding machine for the power requirements of tubular wire over solid.





The quality of the off-brand wires varies greatly and you may find that you may yet need to run it with shielding gas anyway, to protect the arc pool. Personally, I like dual shield II.





Also, on the 'house current' type of smaller machines, the drive rolls are usually designed to be used with wires up to .035';; it is worth taking a peak to make sure, so they don't slip. Otherwise you will have to get larger drive rolls.





As for the sheet metal? How's that working for you? Cause, generally a solid wire works much better on sheet metal, by far. I prefer E70-S





Good Luck,

use a hammer and dolley or find a round object pipe maybee with the right curve radius to bend the metal around. you may need to make the cab cornerin several pieces and weld them in place. lots of patience and some practice helps a lot. use the torch as little as possible.

Aviation Snips or sheet metal shears are very good for cutting sheet metal. LOL! After all that what they are made for. The problem is that there are three to a set. One for cutting straight cuts,one for making cuts to the left and one for cuts to the right. The ones I bought some years ago if I remember correctly were close to twenty dollars each but well worth the cost for me.. As far as Dremels. great tools,I've burned out three of them so far.LOL!.What is the best dremel attachment for cutting sheet metal?
There isn't one - not the best use for a Dremel - get a nibbler or the pair of pliers that cut a narrow slot with one jaw going between two others. Tin snips or aviation snips are great - for flat sheet metal - but they bend the metal and using them on a shaped case is a real hassle.
most cases are thin pressed steel - if you want a quick neat job, take the case (marked up with the hole you want) to a car repair shop, and ask them to use what in UK we call a ';nibbler'; to do a nice clean job, and then deburr it to be sure. Keep any steel swarf a million miles away from your mobo. (see links below)

I want a type of copper that can easily bend but hold shape, not wrinkle, and be easily cut with scissors. and what gauge brass with the same specsI want to make some solder sculptures with copper sheet metal, but i don't know what gauge copper i should us?
Brass in the same gauge as copper is going to be harder to cut and stiffer. Both by the way will ruin scissors for other uses and you may wish to buy a small tin snips with hardened blades.


A bunch will depend on the history of the sheet as both metals work harden, so if it was rolled and not annealed, it will be harder than if annealed. If you hammer or otherwise work the sheet, it will get harder and you will have to heat it with a torch and let it cool. Normally copper and brass are ';pickled'; in a mild acid solution after annealing and before hammering further to knock off oxide.


It depends on what you want to do as to thickness. I would suggest, if you live in the States, going to a hardware or hobby shop that carries the K%26amp;S Metals display.http://www.ksmetals.com/ and get a selection of 4x10'; pieces of the brass (fewer choices in copper) flexing them gently in the store to make a first judgment as to too thin or too thick. If you want something in between what they offer, you will have to go to a non-ferrous metal supplier in a nearby city or online.

Steel boats and rust go hand in hand... get it in dry dock... do the job properly and keep an eye on major problems. they almost invariably rust from the inside out.
Roughly 79 days, 7 hours, 20 minutes, 54 seconds
Use proper coating material according to standards.

Do you mean metal plates to cover the holes left when you remove your door handles on a car or truck? Well, if so, then there are some things that come to mind: If it's to be sold to the public, for them to fit and weld in place, then I would recommend that it not be too thin. The thinner it is, the harder to weld, and if they are not professionals, you might want to stick to heavier guages, like 16. Also, if they might be of the do-it-yourself mindset, they might not bother to have your filler pieces sandblasted or pickeled prior to filling/painting...so it may be better to used Cold Rolled sheet, that has no mill scale oxide on it...or, if your supplier stocks it, hot rolled sheet that has been pickled.





Since this is a small part you are producing, I can see no reason to bother with trying to use a higher-carbon steel. The weld on such a small rectangle would wipe the temper right out of it anyway. Plus, it will cost YOU more in raw material, and possibly wear the dies on your machines faster than low-carbon steel would.





I would avoid galvanized, simply because it's not worth it with all the welding, and there's no sense in subjecting your future customers to the hassle of removing the zinc at the joints, and avoiding the poisonous fumes.





So, I guess we're looking at something that has low carbon content (.010-.015?), and has no mill scale oxide, is NOT galvanized, and is not too thin. I don't know what machine you'll be using, so I don't know if you need to specify that the sheet be completely annealed. I don't know many steel suppliers in my area that stock that anyway. I'm sure they'll have something in this criteria, that will meet your needs.





And, if it was NOT door handle covers for cars that you were referring to, then please ignore everything I said.I want to mass produce fillers for shaved door handles, what is the best sheet metal for the job?
my own guess on this is that you would wantto use 14 or 16 guage basic sheet metal.... so that you don't have a dissimular metal bond and increase the likleyhood of corrosion I wouldn;t use galvinazed since it take some different prepwork and certian primers may not adhere as well

How can I fasten a plastic sheet to a metal computer case?

I'm going to mod my Xbox 360 case, drilling a shape into the metal case with a dremel and then fasten a white sheet (maybe plastic) to the metal case so you can see through but i'm not sure how to fasten it.How can I fasten a plastic sheet to a metal computer case?
3M makes good double stick tape...How can I fasten a plastic sheet to a metal computer case?
I would go with a chemical adhesive, fancy talk for glue. For this application I should think there will be no stress on the piece so simple ';super'; glue from anywhere you shop should do it.


Not substantial enough for you? Use a few pop rivets, easy to do and you can find a pop rivet set cheap. Try Harbor Freight as a source. Of course these will leave bumps from the rivets that might detract from the appearance you are trying to achieve.
