In each question: you place mass m on the mass holder, and released the system from rest. The system includes two pulleys and a long rod with two point masses on it.

a) In procedure 1: if you increase m, the mass on the mass holder, what happens to the following quantities:

- α, the angular accelertion of the pulley.

- I, the moment of inertia of the pulleys-plus-rod system.

In procedure 2: if you move the two masses attached to the rotating rod away from the center of mass of the rod, what happens to the following quantities:

- α, the angular accelertion of the pulley.

- I, the moment of inertia of the pulleys-plus-rod system.

2. The attempt at a solution

For part (a), I thought the answer is α increases, I increases, but it's wrong.

For part (b), I thought the answer is α decreases, I decreases, but it's also wrong.
