When a person stands on tiptoe (a strenuous position), the position of the foot is as shown in Figure. The total gravitational force on the body, Fs, is supported by the force n exerted by the floor on the toes of one foot. A mechanical model of the situation is shown in Figure, where T is the force exerted by the Achilles tendon on the foot and R is the force exerted by the tibia on the foot. Find the values of T, R, and u when Fg= 600 N.
