Name:______________________________________ Session:__________________ Problem 1: A stepped shaft ACB is held against rotation at ends A and B and subjected to a torque T 0 acting at section C . The two segments of the shaft ( AC and CB ) have diameters d A and d B , respectively, and polar moments of inertia I PA and I PB , respectively. The shaft has length L and segment AC has length a . For what ratio a / L will the maximum shear stresses be the same in both segments of the shaft? To make the calculations easier, let the dimensions L A = a and L B = L – a. The answer should be in terms of
