Question

A consulting company submitted a structural design project and they want to be insured by XYZ Insurance Company. XYZ Insurance Company then ask their internal Engineering department to do an engineering analysis to check if the project is worth insuring. Your team has been tasked to perform all acceptable engineering analyses, and most importantly to come up with the acceptable diameter of the pipe. The structure consist of an L-shaped solid cylindrical tube with loads as indicated in the drawing. The material of the structure is made of stainless steel. The material properties are given below. Modulus of Elasticity E Modulus of Rigidity G Poisson's Unit Weight w Material Mpsi Mpsi GPa RatioIbf/in3 Ibf/ft3 kN/m3 GPa 190.0 106 Stainless Steel 27.6 73.1 0.30s 0.280 484 76.0 The ultimate strength of stainless steel is 80 kpsi. In order to meet the NY state safety requirements, a factor of at least 2 is required. The structure must not have a deflection greater than 0.1 inch at point B. 3000 lb JA 3.5 ft 2.5 ft 1000 lb
