A machine component is made of 2024-T4 aluminum. The external loads produce highest operating principle stresses that are estimated to be 18.5ksi, -13.5ksi, and 0ksi. Your client specifies a safety factor to be at least 1.5 for this design and operating loads.
Draw the complete Mohr Circle and (sigma1,sigma2) Plot. What is the safety factor with respect to initial yielding according to the Max Shear Stress Theory and the Max Distortion of Energy Theory? Based on your findings, do you recommend the client change the design and/or loads? why?
