Problem 2 When performing a lying lateral leg raise exercise, the leg abduction muscles must apply enough force to lift the athlete's leg and a weighted ankle band. A simplified diagram of how the forces are applied to the leg is shown below, where O represents the hip joint, C represents the muscle attachment point, A is the center of gravity of the leg, and B is the ankle. Assume the weight of the leg, W, is 80N, a = 5cm, b = 35cm, c = 80cm, 0 = 20", and equilibrium. Solve for the reactions at the hip joint. 150N A O W
