Problem 7: 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 2.05 × 10³ N with an effective perpendicular lever arm of 3.25 cm, producing an angular acceleration of the forearm of 105 rad/s². What is the moment of inertia of the forearm, in kilogram meters squared?
