Standard bowling ball weighs

Reference no: EM13657246

A standard bowling ball weighs 17 pounds. You wish to hold a bowling ball infront 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 suppose that the ball is held 38 cm out from the elbow joint. Let the mass of your forearm be 4.9 kg and assume its center of gravity is located 19 cm 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?
