The Achilles tendon is attached to the rear of the foot as shown in (Figure) . A person elevates himself just barely off the floor on the "ball of one foot." Assume the person has a mass of 76 kg and D is twice as long as d.
1. Find the tension FT in the Achilles tendon (pulling upward).
2. Find the (downward) force FB exerted by the lower leg bone on the foot.
