Physics - one last time

posted by .

A forearm with a mass of 1.2kg supports a put with a mass of 5.44 kg. The forearm is 0.050m long; it's perpendicular to the arm is 0.35m long, the center of gravity is at 0.15m from the elbow. Find the force exerted by rhe biceps and the force on the elbow joint.

    What is a "put" ? Do you mean a "shot" such as is used in a shotput event? The mass is about right for a woman's event (12 pounds).

    I am confused by the description of the arm's position. Is the forearm horizontal? If so, the elbow supports the weight of the shot and of the forearm. It seems to me the force holding the forearm horizontal while holding the shot is exerted by the triceps, not the biceps
