Figure shows the strain-stress curve for a given material. The Young's modulus of the material is G

 

From the given graph for a stress of $150\times {10}^6 {\mathrm{Nm}}^{-2}$ the strain is 0.002.

$\therefore$  $\mathrm{Young}\text{'}\mathrm{s} \mathrm{modulus} \mathrm{Y} = \frac{\mathrm{Stress}}{\mathrm{Strain}}$

$\mathrm{Y} = \frac{150\times {10}^6}{0.002}{\mathrm{Nm}}^{-2} = 7.5\times {10}^{10} {\mathrm{Nm}}^{-2}$
