Question

The plot below shows Stress vs. Strain for some material. Use it to determine the Young's Modulus of the material in \left(\frac{N}{m^2}\right)(

Answer 1

It is a linear relation, for young's modulus we use the next formula

$\text{Young's Modulus= }\frac{Stress}{Strain}$

$Y=\frac{5\times10^{-5}}{0.60}=8\times10^5\text{ N/m}^2$

ANSWER

8x10^5 N/m^2
