Gases are stored at high pressures. A cylinder is very strong and uses less material than a box. The strongest container for the amount of material used is a sphere. The cylinder is a compromise that provides a good strength to material ratio with an easy to transport flat bottom.
A round shape means that each area experiences equal stress. Corners or angles concentrate stress and this causes points of failure.
I really dont know but I will tell you to check out some articles at www.High Beam.com and you can check out HGTV on TV and they always put in insulation!
Because everything always has to be grounded, for safety. If a 'ground' is not available, as in an aircraft, all the external containers for the different items of equipment are all connected together to the local 'earth'.
Because recycling is always the best option against using 'virgin' timber.
You can always use a higher voltage rated capacitor, it will probably just last a little longer.
uhm , instead of obsessing over his feet , doodle on a piece of paper to disctract yourself .
The reason is that the cylindrical configuration turns out more resistant to the inside pressure than the rectangular one. The opposite is also true, the cylindrical configuration withstands a higher outside pressure. That why submarines use such configuration.
Yes, except for all the spheres, pyramids, cones, rectangular boxes, egg shapes, cylinders, etc.
Yes, always
yes
No. Rectangular packing can be better, particularly if the overall area is rectangular.
They are all rectangular but there can also be 4 rectangular faces and 2 square faces. Always 6 in total.
No.
to answer this i must ask you this what does it always okay
Ammonium chloride is easily decomposed and NH3 and HCl are released.
I've always found standard rectangular or square rooms to be boring.I ordered a rectangular cake, you've made it triangular.
It is always a good idea to use original containers for storage of hazardous materials as much as possible.
Not necessarily.
