1. In each question: you place mass m on the mass holder, andreleased the system from rest. The system includes two pulleys anda long rod with two point masses on it. If you increase m, the masson the mass holder, what happens to the following quantities: - a,the angular accelertion of the pulley and I, the moment of inertiaof the pulleys-plus-rod system.
Do they increase, decease, or remain the same?
2.Â Â If you move the two masses attached to therotating rod away from the center of mass of the rod, what happensto the following quantities:
- a, the angular accelertion of the pulley.
- I, the moment of inertia of the pulleys-plus-rodsystem.
Do they increase, decease, or remain the same?
