Question

A flywheel is revolving with a constant angular velocity. A chip of its rim breaks and flies away. What will be the effect on its angular velocity?

Answer 1

Answer:

A flywheel is revolving with a constant angular velocity. A chip of its rim breaks and flies away. The effect on its angular velocity is given by

Explanation:

1. when the chip of the flywheel revolving with a constant angular velocity breaks away, it's mass will decreases.
2. Due to the increase in it's mass ,the moment of inertia of flywheel will decreases.
3. In order to conserve angular momentum,the angular velocity of the flywheel will increases.

Due to the decrease in its mass, the moment of inertia of the flywheel will decrease. To conserve angular momentum, the angular velocity of the flywheel will increase.

According to the Principle of Conservation of Angular Momentum when no external torque acts on a system of particles then the total angular momentum of the system always remain constant.

Angular speed is defined as the rate of change of angular displacement, and it is expressed as follows: ω = θ t.

Angular momentum depends on the rotational velocity of an object, but also its rotational inertia. When an object changes its shape (rotational inertia), its angular velocity will also change if there is no external torque.
