Solution
- When the chip of the rim of a flywheel revolving with a constant angular velocity breaks away, its mass will decrease.
- Due to the decrease in its mass, the moment of inertia of the flywheel will decrease.
- In order to conserve angular momentum, the angular velocity of the flywheel will increase.
