Physics - Elasticity Question with Solution | TestHub

According to Hooke's law, within the elastic limits stress is directly proportional to strain.

i.e. $\mathrm{stress} \propto \mathrm{strain}$ or $\frac{\mathrm{stress}}{\mathrm{strain}}=\mathrm{constant}=\mathrm{E}$

The constant $\mathrm{E}$ is called the modulus of elasticity.
