The torsional assembly of the figure consists of a cold-rolled stainless steel tube connected to a solid cold-rolled brass segment at flange C. The assembly is securely fastened to rigid supports at A and D. The stainless steel tubes(1) and (2) have an outside diameter of 4.0 in.,a wall thickness of 0.140 in., and a shear modulus of G = 12,500 ksi. The solid brass segment (3) has a diameter of 2.00 in. and a shear modulus of G = 5,600 ksi. A concentrated torque of TB = 5kip-ft is applied to the stainless steel pipe at B. Calculate the internal torques in each of the three members (1), (2), and (3).
