Question

Which of the following statements are true? (Select all that apply.) All parts of a wheel rotating about a fixed axis must have the same angular speed. All parts of a wheel rotating about a fixed axis must have the same angular acceleration. All parts of a wheel rotating about a fixed axis must have the same centripetal acceleration. Angular speed and linear velocity have the same dimensions.

Answer 1

Answer:

All parts of a wheel rotating about a fixed axis must have the same angular speed.

All parts of a wheel rotating about a fixed axis must have the same angular acceleration.

Explanation:

In a rigid body in rotation (a rotating wheel) with respect to a fixed axis, each particle on the body turns around the same angle in a certain time interval, having the same angular speed and the same angular acceleration. Otherwise, the wheel will deform, therefore it would not be in equilibrium
