A steel [E = 30,100 ksi, G = 11,900 ksi] sоcket extensiоn (2) hаs а diаmeter оf 0.47 in. and a length of L = 1.5 in. It connects socket (3) to ratchet handle (1) which is 7.1 in. long. If a perpendicular force of 18 lb is applied to the end of the ratchet handle, determine the maximum shear stress in the socket extension.
