The biceps muscle acts in the +y direction at a location of approximately 5.00 cm from the elbow (axis of rotation]. The mass of the forearm-hand system is roughly 2.29 kg with its center-of-mass at approximately 1?.0 cm from the elbow (about half of the length of the forearm-hand system). Determine the biceps muscle force to keep the forearm horizontal. W 15 cm+| (a) 35 cm>l
