A simple torsion-bar spring is shown. The shear stress in the steel [G= 11,500 ksi] shaft is not to exceed 10200 psi, and the vertical deflection of joint D is not to exceed 0.550 in. when a load of P = 3700 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 = 60 in., b = 32 in., and c = 36 in. Answer: d= D B in.
