A person holds a 1.26 N
baseball in his hand, a distance of 34.0 cm from the elbow joint,
as shown in the figure(Figure 1). The biceps, attached at a
distance of 2.75 cm from the elbow, exerts an upward force on the
forearm. Consider the forearm and hand to be a uniform rod with a
mass of 1.40 kg . Suppose the biceps exert just enough upward force
to keep the system in static equilibrium.
