Question
A simple torsion-bar spring is shown. The shear stress in the steel [G = 11,500 ksi] shaft is not to exceed 11400 psi, and the vertical deflection of joint D is not to exceed 0.475 in. when a load of P = 2700 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 = 68 in., b = 24 in., and c = 30 in.
