A simple torsion-bar spring is shown. The shear stress in the steel [G-11,500 ksi] shaft is not to exceed 8600 psi, and the vertical
deflection of joint D is not to exceed 0.400 in. when a load of P-3300 lb is applied. Neglect the bending of the shaft and assume that
the bearing at Callows the shaft to rotate freely. Determine the minimum diameter required for the shaft. Use dimensions of a - 66
in., b-38 in., and c-24 in.
