The thin-walled pressure vessel as shown is being transported by hanging it from a high- tension steel cable. The pressure vessel is manufactured by rolling a 34-in steel plate into a cylinder with 2.5 ft outside diameter and 6 ft height then sealing it by two rigid steel caps with diameter of 2.5 ft and thickness 3 in. When the pressure in the vessel is 500 psi, determine the maximum longitudinal and circumferential stresses in the vessel. Steel has a density 500 lb/ft3 . Neglect the weight of the gas
