Match lists-I and II
 

List-I	List-II
a) spring constant	e) $\frac{(\text{ stress }{)}^2}{2Y}$
b) Tensile strength	f) $\frac{\Delta P}{\Delta V/V}$
c) Bulk modulus	g) Breaking stress
d) Potential energy per unit volume	h) $\frac{AY}{L}$

 

For a rod under axial loading, 

$x=\frac{FL}{AY}\Rightarrow F=\left(\frac{AY}{L}\right)x$

$\therefore F\propto x$

and spring constant = AY/L. Tensile strength of a material is the breaking stress at which a body made of that material breaks under tensile force. 

By Hooke's Law, 

$\Delta P=B\times \left(-\frac{\Delta V}{V}\right)$

Elastic potential energy stored per unit volume = $\frac{1}{2}\times ϵ\times \sigma =\frac{1}{2}\times \left(\frac{\sigma }{Y}\right)\times \sigma =\frac{{\sigma }^2}{2Y}$

where $\sigma$= stress.
