Question

what is young,s modulus of elasticity?....​

Answer 1

Y = longitudinal stress / longitudinal strain

.

hope it help

definition-

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

thanku

..btw u r neet aspirant??

Answer 2

Explanation:

Young's modulus is a measure of the ability of a material to withstand changes in length when under lengthwise tension or compression. Sometimes referred to as the modulus of elasticity, Young's modulus is equal to the longitudinal stress divided by the strain.Young's modulus E, the Young modulus or the modulus of elasticity in tension, is a mechanical property that measures the tensile stiffness of a solid material.
