Body and its types
What is Body?
Body is a matter that is bounded by a closed
surface.
What are types of body?
Rigid body
Flexible body (or) Elastic body
What is Rigid Body?
I explain this with an example. Consider
mobile phone. Now you choose any two points on your phone. Now you shake your
phone. Does the distance between the assumed two points changed? It doesn’t.
That means for a rigid body distance between
its points or particles is held constant even though if they undergo any
deformation. Practically the distance between particles will be changed. For a
rigid body the value of deformation is negligible.
What is Elastic body?
For an
elastic body, distance between the particles changes with respect to forces
that it is subjected.
