Question

What is hook's law? explain

Answer 1

hooks law is also the fundamental principlebehind the spring scale, the manometer, and the balance wheel of the mechanical clock. The modern theory of elasticity generalizes Hooke's law to say that the strain (deformation) of an elastic object or material is proportional to the stress applied to it.

Answer 2

$\huge{\text{\underline{\green{Hook's \; Law}}}}$

Statement:

Within the elastic limit, the stress is directly proportional to the strain.

i.e., stress or strain

Explanation:

Stress = E × Strain

$\frac{Stress}{Strain} = E$

When E is the proportionality constant and is known as modulus of elasticity.

Note: The SI unit of modulus of elasticity is $Nm^{-2}$.
