If you hold your arm outstretched with your palm upward, the force to keep your arm from falling comes from your deltoid muscle. Assume that the arm with hand has mass 4.25 kg and the distances and angles shown. What force must the deltoid muscle provide to keep the arm in this position, in Newtons? Use g = 10.0 m/s2. the answer is 367, please explain how?
