Question

Figure shows a graph of stress vs strain for four materials
The materials with heighest value of youngs modulus is

• A. $A$
• B. $B$
• C. $C$
• D. $D$

Answer 1

The correct option is D $D$

$\begin{array}{c}\text{We Know}\\ \text{young's modulus}\left(Y\right)=\frac{\text{Stress}}{\text{strain}}\\ \text{so,}{Y}_D>Y_c>Y_B>Y_A\end{array}$

D has highest value of youngs modulus

Hence option D is correct
