A 60 kg gymnast holds an iron cross position on the rings. In this position, the gymnast's arms are abducted 90 degrees and his trunk and legs are vertical. The horizontal distance from each ring to the gymnast's closest shoulder is 0.60 m. The gymnast is in static equilibrium.

a. What vertical reaction force does each ring exert on each hand?

b. What torque is exerted by the right ring about the right shoulder joint?

c. How much torque must the right shoulder adductor muscles produce to maintain the iron cross position?

d. If the moment arm of the right shoulder adductor muscles about the shoulder joint is 5 cm, how much force must these muscles produce to maintain the iron cross?
