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. :)

My father is trying to sell his sheet metal company in Alaska. Where is the best place to advertise for this?

Do not advertise the company is for sale. His competitors will use the information to their benefit and his harm, plus as soon as you list the business, the value goes down.





Seek a qualified advisor to help you effectively and confidentially market the business for its maximum value.





Good Luck.

Can a piece of painted, sheet-metal be made to look (indistinguishable from) a piece 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.

How many inches is an 11 gage piece of sheet metal?

Also how thick is 7 gage sheet metal. Thanks for the helpHow many inches is an 11 gage piece of sheet metal?
Well the title answer for 11 gauge is 1/8


the thickness of 7 gauge is 3/16


There is a site called Jedi.Com that has a whole list of gauge equivilat to fraction, decimal and MM. (it takes a little searching of the site to find it though. I just have a print out now so i dont remember how i got there.) good luck.How many inches is an 11 gage piece of sheet metal?
It depends on the material





11 Gauge thickness standard steel is actually .1196 inches thick


so the 1/8 is only the nominal not the actual thickness





7 gauge thickness (see the chart)





Great Question
0.1196 inches

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.
That darn heat shield on the exhaust (iff that counts)

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. Everything on large construction sites are unionized, this is not the best time for construction but there is still commercial and residential going up. just not as much as previous times.

With regards to the rolling direction, which gives the strongest strength to sheet metal?

Rolling perpendicular to the direction of grain.

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?
? I guess you can feel it. What are you trying to do, paint it? Fresh sheet metal is not rough at all. It's very smooth.

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!!!
I think you can.

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.

OK so you rear ended someone, at the shop those fixes also show up other stuff when we dis assemble. for paint and the works look at around 12 - 1500, but you can always buy a tool kit go to the junkyard and maybe get lucky finding a civic same color and do it yourself.
