A pressure vessel is exposed to a combination of loads as shown below. The vessel (diameter 100 mm) has a wall thickness of 3 mm. Address the following: (a) If the yield strength of the material is 144 MPa, determine the largest tension force P with respect to a factor of safety of 2 applied to the distortional energy theory. (b) If the applied torque and tension load were removed, determine the minimum wall thickness using a factor of safety of 1.75 with respect to the distortional energy theory. Illustrate you results using an appropriate yield envelope. T T P p = 3.5 MPa P T=450 N-m
