The pressure vessel in Figure 1 is subject to an internal pressure of 164.98bar.

The vessel has an outside diameter of 180mm, and a wall thickness of 11mm.

A torque of 9561Nm is also applied to the vessel in the direction shown in the figure. The vessel has a yield strength of 137MPa. Using clockwise positive polar co-ordinates:

Determine the Maximum Shear Stress in the vessel wall (Answer in MPa).

Determine the Longitudinal Stress in the Vessel wall (Answer in MPa ).

Determine the Circumferential Stress in the vessel wall (Answer in GPa).

Determine the Maximum Torque that can be applied to the vessel (Answer in Nm).

Determine the Maximum Internal Pressure that can be applied to the vessel (Answer in kbar).
