Problem 1: 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 2.05x103 N with an effective perpendicular lever arm of 2.75 cm, producing an angular acceleration of the forearm of 110 rad/s2. What is the moment of inertia of the forearm, in kilogram meters squared? Problem 2: A uniform beam of length L and mass my is supported by two pillars located L/3 from either end, as shown in the figure. A duck of mass mp stands on one end. A scale is placed under each pillar. The entire system is in equilibrium. a. Enter an expression, in terms of defined quantities and g, for the force that the scale under right pillar shows. b. Enter an expression, in terms of defined quantities and g, for the force that the scale under left pillar shows. c. Enter an expression, in terms of defined quantities and g, for the sum of the scale readings. L/3 L/3
