2. The mass of the building crane's boom in Figure2 is 9000kg. Its weight acts at G. The sum of the moments about P due to the boom's weight, the force exerted at B by the cable AB, and the force exerted at C by the cable AC is zero. Assuming that the tensions in cables AB and AC are equal, determine the tension in these cables. 8m Вoom P 16 m 38 m 56 m Figure 2
