# Hook’s Law Statement:

Stress is directly proportional to the strain until load on material is within its elastic limit.

**Mathematically,**

Stress ∞ Strain

Stress = A constant x strain

\(frac{Stress}{Strain}= Constant\)Constant is represented by **E** & is known as **Young’s Modulus**.

## Hook’s Law Formula

\(frac{Stress}{Strain}= E\)[frac{f}{e}=E]
