Answer 1

Putty or mud is an example of a perfectly plastic body.

1. Perfectly plastic bodies are those that retain their distorted shape or size after external pressures applied to them have been released.
2. Partially elastic bodies are those that partially return to their former shape or size when external forces are eliminated.
3. The shape or size of mud or putty is now altered when force is applied, and the body does not return to its original state when the force is removed. Only perfectly plastic bodies, as already established, exhibit this feature.
4. Additionally, many elasticity moduli types are used to measure elasticity.
5. The ratio of stress to strain given to a body under various variations in dimension is what makes up an elastic modulus.
6. Young's Modulus, Shear Modulus, and Bulk Modulus are the three forms of elastic moduli. Since Young's modulus or longitudinal stress by strain for mud or putty is almost zero, they are theoretically proven to be almost ideal plastic bodies.
7. Hence, putty or mud is an example of a perfectly plastic body.

Therefore, putty or mud is an example of a perfectly plastic body.
