PROBLEM 3.47 Solve Prob. 3.46, assuming that both shafts are made of a brass with G = 5.6 × 106 psi and ?all = 8 ksi. PROBLEM 3.46 The design specifications for the gear-and-shaft system shown require that the same diameter be used for both shafts and that the angle through which pulley A will rotate when subjected to a 2-kip·in. torque TA while pulley D is held fixed will not exceed 7.5°. Determine the required diameter of the shafts if both shafts are made of a steel with G = 11.2 × 106 psi and ?all = 12 ksi.
