Consider the traction device illustrated. A weight W2 is suspended on a long cable that passes over 4 pulleys. The cable is attached to the leg at B, which coincides with position along the leg of the center of gravity of the leg B and cast. A second cable is connected to the leg at point A and to one of the pulleys such that point A and the center of the pulley form a horizontal line. The distance e between A and B is 50 cm. The total weight of the leg and cast is W1=200N, and the angle a is 75.5. Determine the tensions in the cables, the angle B, and the value of the weight W2 required to maintain the leg in the position shown
