This resource is useful for introducing components of Engineering Design (ETS) from the Next Generation Science . Theoretically, a spherical pressure vessel has approximately twice the strength of a cylindrical pressure vessel with the same wall thickness Its still strong, although this geometry does give up a little of the rigidity of the I-beam. The circle is the most powerful form because it maintains continuous pressure. This is because stress is distributed evenly along the arc instead of concentrating at any one point, which makes it the strongest structural shape. It is shown that the cross-. This type of triangle has two sides of the same length, and a third side of a different length. And this statement is fairly easy to prove. This is also whycylinders are able to bend while maintaining most of their strength. I-beam: An I-beam often has a thinner center web, which means it is often not able to take as much force as an h-beam. The arc (think: circle) is the strongest structural shape, and in nature, the sphere is the strongest 3-d shape.
