Class 11 physics​

Answer 1

Answer:

:-Young's modulus is a measure of the ability of a material to withstand changes in length when under lengthwise tension or compression.

:- Elasticity is the ability of an object or material to resume its normal shape after being stretched or compressed; stretchiness.

:- Plasticity is the ability of a solid material to undergo permanent deformation, a non-reversible change of shape in response to applied forces.

:- Modulus of elasticity is a quantity that measures an object or substance's resistance to being deformed elastically when a stress is applied to it. The elastic modulus of an object is defined as the slope of its stress–strain curve in the elastic deformation region: A stiffer material will have a higher elastic modulus

Answer 2

Young's modulus (E) is defined as the ratio of the stress applied to the material along the longitudinal axis of the specimen tested and the deformation or strain, measured on that same axis. Young's Modulus is also known as tensile modulus, elastic modulus or modulus of elasticity.Elasticity is the property of the solid material by virtue of which it tends to regain its shape after the removal of external load. Plasticity is the property of the solid material by virtue of which it tends to retain its deformed shape even after the removal of external load.Definition of modulus of elasticity. : the ratio of the stress in a body to the corresponding strain (as in bulk modulus, shear modulus, and Young's modulus) — called also coefficient of elasticity, elastic modulus.
