A rigid link is: a joint between Structural members which does not permit relative motion between them.
( t = I a ) Rotational motion and centripetal acceleration. This is defined by its equations of motion.
rigid body has definite shape but deformable body does not have .

Rotation around a point, or spherical motion, is the motion of a rigid body during which one of its points O remains fixed, while all the other points move along the surface of spheres with their center at point O. During such rotation of a rigid body, any elementary displacement of the body is an elementary rotation around some axis passing through point O and called the instantaneous axis of rotation. This axis, unlike a fixed axis, is constantly changing its direction with time. As a result, the rotational motion of a rigid body consists of a series of elementary rotations about instantaneous axes that are constantly changing direction. An example of such rotation is the movement of a gyroscope.

The key difference between a particle and a rigid body is that a particle can undergo only translational motion whereas a rigid body can undergo both translational and rotational motion
rigid transformation is for same modality(CT-CT) nad it can only perform translation, rotation and scaling translation. whereas non rigid for multimodality and it can do streching and shriking too. it use demon algorithm .
Movement of a shape can involve flexing - for example, a square frame being flexed into a rhombus. Rigid motion excludes such motion: the shape of the moving object does not change.

the force of attraction between its molecules becomes strong enough to overcome the energy of motion that its molecules have when the substance is in its liquid state, molecules are locked into rigid crystalline formations.
