A simple torsion-bar spring is shown. The shear stress in the steel [G = 11,500 ksi] shaft is not to exceed 11800 psi, and the vertical deflection of joint D is not to exceed 0.600 in. when a load of P = 2900 lb is applied. Neglect the bending of the shaft and assume that the bearing at C allows the shaft to rotate freely. Determine

A simple torsion-bar spring is shown. The shear stress in the steel [G = 11,500 ksi] shaft is not to exceed 11800 psi, and the vertical deflection of joint D is not to exceed 0.600 in. when a load of P = 2900 lb is applied. Neglect the bending of the shaft and assume that the bearing at C allows the shaft to rotate freely. Determine the minimum diameter required for the shaft. Use dimensions of a = 92 in., b = 40 in., and c = 34 in.
