Extracted text: 2. (20%) In the rotary system as below, where tire mass m, =12 kg, axle mass m, = 3 kg, and radius r= 0.30 m. 1) The mass of all the other parts is ignorable. What is the moment of inertia J for the overall system with respect to the center? 2) What is the torque T for an external force F 25 N working on the top edge of the tire as indicated in Fig. 1, where the direction of the force is perpendicular to the radius? 3) What is the angular acceleration of the system? m, Fig 1.
