The boom AC is a 4-in. square steel tube with a wall thickness of 0.25 in. The boom is supported by the 0.67-in .-diameter pin at A, and the 0.26-in .-diameter cable BC. Neglecting the weight of the boom, determine the shear stress in the pin (in psi) if P = 5411 lb. Round off the final answer to two decimal places.
