Question

Select the correct statement on the basis of the given graph :

• A. Young's modulus of A is greater but it is less ductile
• B. Young's modulus of A is greater and it is more ductile
• C. Young's modulus of A is less and it is less ductile
• D. Young's modulus of A is less but it is more ductile

Answer 1

The correct option is A Young's modulus of A is greater but it is less ductile

$Y=\frac{stress}{strain}$
For same strain $(stress{)}_A>(stress{)}_B$
$\therefore Y_A>Y_B$
$\therefore$ Breaking point of B > Breaking point of A
So, A is less ductile.
