Q-3. The figure shows a clutch-testing apparatus. An axial load P is applied to a steel shaft as shown. The torque T induced by the clutch face onto the shaft is found to be 0.55P. The shaft has a diameter of 1.2 in. and is made of cold-drawn AISI 1040 steel. S = 71 kpsi. Using a design factor of 4, determine the maximum load P using: a. Maximum shear stress theory b. Distortion energy theory. 7 points.
