Dynamics of rotational Motion about fixed axis of rotation

Questions based on dynamics of rotational Motion about fixed axis

A rigid body not fixed in some way can have either pure translation or a combination of translation and rotation. In rotation about a fixed axis, every particle of the rigid body moves in a circle which lies in a plane perpendicular to the axis and has its centre on the axis.

Dynamics of rotational Motion (General Rigid Body Motion)-2

A body performs rotational motion about the given axis, particles perform U.C.M. with same angular velocity. The particles at different positions have

Assertion: If the head of a right handed screw rotates with the body, the screw advances in the direction of the angular velocty. Reason: For rotation about a fixed axis, the angular velocity vector lies along the axis of rotation.
