Rigid Body definition | Important Points about rigid body

Rigid body Definition: A body is said to be rigid if relative displacement or relative displacements or relative deformations of various points of a body is negligibly small.

For a certain load body may be rigid but if we increase the intensity of load it may deform because it exceeds its allowable limit.

Important Points:

1. No object is absolute rigid.
2. During analysis we assume all structures as rigid.
3. If structure is very rigid then it becomes brittle and can be collapsed.
