Question

Describe the principle measurement of Young's Modulus

Answer 1

In solid mechanics, Young's modulus is defines as the ratio of the longitudinal stress over longitudinal strain, in the range of elasticity the Hook's law holds (stress is directly proportional to strain). It is a measure of stiffness ofelastic material.

Answer 2

the young modulus defines as the ratio of longitudinal stress over longitudinal strain, in the range of elastcity the hooks law holds ( stress is directly proportional to strain)
