Question

what is young's modules?

Answer 1

Young's modulus(E) is the property of a material which gives the measure of its elasticity.

It is given by the slope of the stress-strain curve of the material.
If the material is more elastic, the young's modulus is high.

mathematically, $E= \lim_{\delta \epsilon \to 0} \frac{\delta \sigma}{\delta \epsilon}$

Answer 2

Young's modulus, which is also known as the elastic modulus, is a mechanical property of linear elastic solid materials. It defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material.
