Consider the steel pressure vessel shown in Figure 1, intended to withstand an internalpressure of 40 MPa. The vessel has an outer diameter of 300 mm, an overall length of 500mm and a wall thickness of 30 mm. There is a 30 mm fillet radius where the interior wallsurface joins the end caps, as shown in the section view in Figure 1. The vessel is made ofASTM A27 steel. Use ANSYS Workbench to simulate this component and comment on itssuitability for production given the loading conditions detailed above.

* Your answer is incorrect. The composite shaft consists of two steel pipes that are connected at flange B and securely attached to rigid walls at A and C. Steel pipe (1) has an outside diameter of 8.625 in., a wall thickness of 2.6 in., and a length of L₁ = 17 ft. Steel pipe (2) has an outside diameter of 5.8125 in., a wall thickness of 1.14 in., and a length of L₂ = 24 ft. Both pipes have a shear modulus of 12900 ksi. If a concentrated torque of 30 kip-ft is applied to flange B, determine: (a) the maximum shear stress magnitudes T₁, T2 in pipes (1) and (2).
