Find the Young's modulus of the wire whose stress-strain curve is as shown in the following figure Find the Young's modulus of the wire whose stress-strain curve is as shown in the following figure

Options

  1. A8×1011Nm−28 \times 10^{11} \mathrm{Nm}^{-2}
  2. B24×1011Nm−224 \times 10^{11} \mathrm{Nm}^{-2}
  3. C10×1011Nm−210 \times 10^{11} \mathrm{Nm}^{-2}
  4. D2×1011Nm−22 \times 10^{11} \mathrm{Nm}^{-2}

Correct answer

D. 2×1011Nm−22 \times 10^{11} \mathrm{Nm}^{-2}

Step-by-step solution

We know that, stress =Y×=Y \times strain (Under proportional limit) Now Young's modulus, Y= Stress  Strain =(8−0)×107(4−0)×10−4=2×1011Y=\frac{\text{ Stress }}{\text{ Strain }}=\frac{(8-0) \times 10^7}{(4-0) \times 10^{-4}} =2 \times 10^{11}Nm−2\mathrm{Nm}^{-2}
