Difference between rigid and non rigid body on the basis of modulus?

1.	Difference between rigid and non rigid body on the basis of modulus?
Answer» Young’s Modulus Elasticity shows the stiffness of a material. If a material has low Elasticity such as a rubber band you can deform it easily. If a material has high Elasticity such as steel, it is hard to deform. Now rigid body can also be defined with Young’s Modulus. A rigid body is such a body that it has infinite Elasticity. All non rigid materials have different stifnesses(Elasticity), like the previous example of rubber and steel.
