1. (2 pts) what are the two loading conditions (a) and (b) in this lab? 2. (3pts) where on the hollow circular shaft and which strain gage do you expect to see the largest positive normal strain readings under loading condition (b)? explain why. 3. (5pts) for each of the three points a, b and c on the hollow circular shaft under loading condition (b), show the combined stress distributions of the torsional shear stress and the cross-shear stress. draw necessary illustrations and explain. 4. (10 pts) derive the following expression (equation (3.3) in lab manual) for maximum q at neutral axis of the hollow circular shaft for this lab:
