Question

4. When a person stands on tiptoe (a strenuous position), the position of the foot is as shown in the figure below (a). The total gravitational force on the body, ? ?, is supported by the force ? ⃗ exerted by the floor on the toes of one foot. A mechanical model of the situation is shown in the figure below (b), where ? ⃗ is the force exerted by the Achilles tendon on the foot and ? ⃗ is the force exerted by the tibia on the foot. Find the values of T, R, and ? when ? ? = ? = 700 N.
