A simple torsion-bar spring is shown. The shear stress in the steel [G= 11,500 ksi] shaft is not to exceed 10800 psi, and the vertical deflection of joint D is not to exceed 0.425 in. when a load of P = 3100 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 = 84 in., b = 32 in., and c = 36 in. Part 1 Answer: D T= i P B Calculate the torque being applied to the shaft at point B. b lb-in
