A stainless steel pressure vessel is made of long tubing having an outside diameter of 1.5 in and a wall thickness of 1/4 in. (1) what maximum internal pressure (zero external pressure) can the cylinder carry if the permissible tangential stress is 60 ksi and the theory for thick walled vessels is assumed to apply? (2) What maximum external pressure (zero internal pressure) can the cylinder carry assume the same permissible tangential stress limit applies?
