Question

What is young modulus and elasticity.

Answer 1

An elastic modulus is a quantity that measures an object or substances 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..
Young's modulus describes tensile elasticity, or the tendency of an object to deform along an axis when Opposing forces are applied along axis ; it is defined as the ratio of tensile stress to tensile strain .It is often referred to simply as elastic modulus...

Answer 2

Answer:

A measure of elasticity, equal to the ratio of the stress acting on a substance to the strain produced is called youngs modulus
