The thin$-$walled pressure vessel shown is capped by two rigid plates. The fluid pressure inside the vessel is $3\mathrm{.}6$ MPa. The inner diameter is $600$ mm$,$ wall thickness is $8$ mm$.$ The vessel is also being compressed with an axial force, F$=100$kN$.$ Torque is $35$kN$$m$.$ Determine the absolute maximum shear stress at a point on the outside surface of the vessel.
