A 68.4 kg man stands on his toes by exerting an upward force through the Achilles tendon, as shown in the figure. Part (a) In units of newtons, what is the magnitude of the force through the Achilles tendon if he stands on one foot? Part (b) Calculate the force in units of newtons at the pivot of the simplified lever system shown. That force is representative of forces in the ankle joint.

A standpipe in a water-supply system (see figure) is 12 ft in diameter and 6 in. thick. Two horizontal pipes carry water out of the standpipe; each is 2 ft in diameter and 1 in. thick. When the system is shut down and water fills the pipes but is not moving, the hoop stress at the bottom of the standpipe is 130 psi, (a) What is the height h of the water in the standpipe? (b) If the bottoms of the pipes are at the same elevation as the bottom of the stand pipe. what is the hoop stress in the pipes?
