The Achilles tendon is attached to the rear of the foot as shown in (Figure 1) . A person elevates himself just barely off the floor on the "ball of one foot." Assume the person has a mass of 65kg and D is twice as long as d.
Find the tension FT in the Achilles tendon (pulling upward).
Find the (downward) force FB exerted by the lower leg bone on the foot.
