Problem 42

When a person stands on tiptoe on one foot (a strenuous position), the position of the foot is as shown in Figure P12.42a. The total gravitational force F S g on the body is supported by the normal force n S exerted by the floor on the toes of one foot. A mechanical model of the situation is shown in Figure P12.42b, where T S is the force exerted on the foot by the Achilles tendon and R S is the force exerted on the foot by the tibia. Find the values of T, R, and u when Fg 5 700 N.
