1.- Steel element AC corresponds to a 4-in square tubular section boom and a wall thickness of 0.25 in. The boom is supported by the 0.5-in-diameter pin at A, and the 0.375-in-diameter cable. The allowable stresses are 25 ksi for the cable, 18 ksi for the boom, and 13.6 ksi for shear in the pin. If a factor of safety of 2.5 is required, neglecting the weight of the boom, determine the allowable load P that can be applied. (SEE FIGURE 1) FIG 4 in. 3.5 in. Detail at A 1 0.5-in. dia.
