Question

define hookes law and modulus of elasticity

Answer 1

hookes law is known a stress is directly propotional to strain

stress ∝ strain

there are three type of elasticity

1. young's modulus

2.bulk modulus

3.shear modulus

Answer 2

Hey brainly user !

Here is your answer

$\color{blue}\huge\bold\star\underline\mathcal{Hooke's\:law\:of\:elasticity}\star$

Within the elastic limit, stress is directly proportional to strain

∴Stress ⋉ Strain

⇛Stress =E(strain)

Here E is called as modulus of elasticity
