Question

A thin-walled spherical vessel, which is made of AISI C1020, as rolled steel has a 
diameter of 2.5 ft. The joint efficiency of the vessel is 80%. Internal pressure of the gas 
inside the vessel varies continuously from 200 psi to 400 psi. If for a Factor of Safety of 
1.75 based on Soderberg criterion and the surface of the vessel is polished, find the 
minimum safe thickness of the vessel.

2. A thin-walled spherical vessel, which is made of AISI C1020, as rolled steel has a
diameter of 2.5 ft. The joint efficiency of the vessel is 80%. Internal pressure of the gas
inside the vessel varies continuously from 200 psi to 400 psi. If for a Factor of Safety of
1.75 based on Soderberg criterion and the surface of the vessel is polished, find the
minimum safe thickness of the vessel.
