How can we say that a rigid body is rotating in a fixed axis?
The pure rotational motion: The rigid body in such a motion rotates about a fixed axis that is perpendicular to a fixed plane. In other words, the axis is fixed and does not move or change its direction relative to an inertial frame of reference.

Is axis of rotation fixed?
Purely rotational motion occurs if every particle in the body moves in a circle about a single line. This line is called the axis of rotation. Then the radius vectors from the axis to all particles undergo the same angular displacement at the same time. The axis of rotation need not go through the body.
What are the examples of Rigidbody?
A rigid body is an idealization of a solid body in which deformation is neglected. In other words, the distance between any two given points of a rigid body remains constant in time regardless of external forces exerted on it. Example: A metal rod in an example of rigid body.
What is rigid body motion?
Rigid body motion. A rigid body is a system of particles in which the distances between the particles do not vary. To describe the motion of a rigid body we use two systems of coordinates, a space-fixed system X, Y, Z, and a moving system x, y, z, which is rigidly fixed in the body and participates in its motion.
What is an example of a rigid motion?
Translations, reflections, and rotations are examples of rigid motions, which are, intuitively, rules of moving points in the plane in such a way that preserves distance. For the sake of brevity, these three rigid motions will be referred to exclusively as the basic rigid motions.
What is rigid body dynamics?
RIGID BODY DYNAMICS. What are Rigid Body Dynamics – A subset of computer simulation that deals with how to represent and implement the animation or dynamic simulation of a rigid collection of points.
What is rigid body mechanics?
Definition of ‘rigid body’. rigid body in Mechanical Engineering. A rigid body is a body that does not deform or vibrate. Continuum mechanics deals with deformable bodies, as opposed to rigid bodies.
