3. A yo-yo-shaped device mounted on a frictionless rotation axis is used to lift a 30 kg box. The outer radius R of the device is 0.5 m, and the radius r of the hub is 0.2 m. A constant horizontal force G of magnitude 140 N is applied to a rope wrapped around the outside of the device. As a consequence, the box (which is suspended from a rope wrapped around the hub) has an upward acceleration of magnitude 0.8 m/s². G Hub R Yo-yo-shaped device Rigid mount Rope 3A. (5 points) Provide the free body diagram of the yo-yo-shaped device. 3B. (5 points) Provide the free body diagram of the box. 3C. (5 points) Calculate the torque produced by the weight of the yo-yo-shaped device about the axis of rotation. 3D. (10 points) Calculate the tension force on the rope. Calculate the torque produced by the tension about the axis of rotation. 3E. (10 points) Calculate the momentum of inertia of the device about its axis of rotation.
