Question

please help me with the shear, moment and torque diagrams

and the Mohr’s circle

also, is this project worth insuring?

Thank you.

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 al 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 Welght w Mpsi Material Stainless Steel 106 73.1 0.305 0.280 484 76.0 27.6 73.1 0.305 0.280 48476.0 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 Ib TA 3.5 ft 2.5 ft 1000 b Project Scopes. In your analysis, you must provide the following 1. Free-Body diagram(s) 2.

with the stress calculated in the portion 3 we can draw the Mohr's circle . Only critical points need to be considered . Here point O and B need to be considered.

A better way to design these things are by using hollow shafts . Whenever direct stress is not too large and we have to design for rigidity criterion we would like to concentrate more mass away from neutral axis . So that I or J value comes larger with less material consumption.
