The triceps muscle in the back of the upper arm is primarily used to extend the forearm. Suppose this muscle in a professional boxer exerts a force of 2.25 × 103 N with an effective perpendicular lever arm of 2.75 cm, producing an angular acceleration of the forearm of 145 rad/s2. What is the moment of inertia of the boxer’s forearm?
