Question

What bodies does not get deformed under action of force?​

Answer 1

A model of a rigid body is an idealized example of an object that does not deform under the actions of external forces. It is very useful when analyzing mechanical systems—and many physical objects are indeed rigid to a great extent.

Answer 2

Answer:

Deforming force is the force which displaces a body from its original position or configuration either by changing location or shape. Eg: A pencil which is broken by applying force. Restoring force tends to move the place of the body back to its original position or configuration

Explanation:

First, the object returns to its original shape when the force is removed—that is, the deformation is elastic for small deformations. Second, the size of the deformation is proportional to the force—that is, for small deformations, Hooke's law is obeyed. Elastic materials, and objects such as springs, change shape when a force is exerted on them: stretching happens when the material or object is pulled. compression happens when the material or object is squashed.
