The pressure tank shown below can be considered to be a thin walled cylindrical tank with spherical end caps. It has a diameter of 5.000 feet, with a cylindrical wall thickness of 0.5000 inches and has spherical end caps. Find the thickness of the spherical end caps, so that they have the same maximum stress in the metal as the maximum stress in the cylindrical wall. The same type of metal will be the...
