Consider the structure below made of a 25-mm-diameter round rod with static, mutually perpendicular loads of 1000 N and 500 N applied at its end (Cross- section A). The other end (Cross-Section B) is fixed. Address the following questions: a) At end B, compute the stresses at the critical location within the cross-section. Ignore transverse shear and any stress concentrations. b) Show stresses on a properly oriented element and draw the Mohr's circle. c) Apply Tresca theory for yielding and pick up one material suitable for this design using the table given below. d) Draw Tresca yield locus and locate the point of operation on it.
