Approximately what force, FM, must the extensor muscle in the upper arm exert on the lower arm to hold a 6.9 kg shot put (Fig. 9-66)? Assume the lower arm has a mass of 2.8 kg and its CG is 13.0 cm from the pivot point.

It depends upon where the muscle is attached to the bone. The figure is needed to answer the question.
