The boom AC is a 120 mm square steel tube with a wall thickness of 7.5 mm. The boom is supported by the 15-mm-diameter pin at A, and the 11.25-mm-diameter cable BC. the working stresses are 150 MPa for the cable, 108 MPa for the boom, and 81.6 Mpa for shear in the pin. Determine the largest P, in kN, that can be applied as shown if the shear stress in the cable is not exceeded
