“A standard bowling ball weighs 18 pounds. You wish to hold a bowling ball in front of you, with the elbow bent at a right angle. Suppose that your biceps attaches to your forearm at 2.5 cm out from the elbow joint, and that your biceps muscle pulls vertically upward, that is, it acts at right angles to the forearm. Also assume that the ball is held 38 cm out from the elbow joint. Let the mass of your forearm be 4.6 kg and suppose its center of gravity is located 19cm out from the elbow joint. How much force should your biceps muscle apply to forearm in order to hold out the bowling ball at the desired angle?
