Three identical gears are connected in a line. A constant torque is provided to the leftmost gear. a.) Find the rotational equations of motion for all three gears and the system. b.) Show the total kinetic energy equation for the rotational motions of the system, and how much belongs to each gear. c.) Show the total angular momentum equation for the system, and how much belongs to each gear. d.) Show how the total angular momentum of the system would change if a fourth gear were added on the right end of the line.
