Question

A solid steel shaft ABCDE turns freely in bearings at points A and E. The shaft is driven by the gear at C,
which applies a torque T2 = 325lb−ft. Gears at B and D are driven by the shaft and have resisting torques
T1 = 200lb − ft and T3 = 125lb − ft, respectively. Segments BC and CD have lengths LBC = 20 in. and
LCD = 15 in. and the shear modulus G = 11, 600ksi. Determine the minimum required diameter (d) of
the shaft if the allowable shear stress τa = 6ksi. Also calculate the angle of twist between gears B and D.
