Skills for analyzing situations using equilibrium conditions

Hamstring You are exercising your hamstring muscle (the large muscle in the back of the thigh). You use an elastic cord attached to a hook on the wall while keeping your leg in a bent position (Figure P7.43). Determine the magnitude of the tension force uT H on L exerted by the hamstring muscles on the leg and the magnitude of compression force u FF on B at the knee joint that the femur exerts on the calf bone. The cord exerts a 20-lb force u FC on F on the foot.
