A steel [E = 30,200 ksi, G = 11,800 ksi] socket extension (2) has a diameter of 0.48 in. and a length of L = 1.8 in. It connects socket (3) to ratchet handle (1) which is 7.3 in. long. If a perpendicular force of 19 lb is applied to the end of the ratchet handle, determine the maximum shear stress in the socket extension.
