A hollow shaft with an outside diameter of 142 mm and an inside diameter of 128 mm is subjected to both a torque of T = 7 kN-m and an axial tension load of P = 90 kN, as shown in Figure. Determine • The normal and shear stresses at point H and show them on a stress element. • The principal planes and stresses, and max shear stress at point H.
