If S is stress and Y is Young's modulus of material of a wire, the energy stored per unit volume of the wire is :

Answer»

`2.5^(2)Y`
`(S^(2))/(2Y)`
`(2Y)/(S^(2))`
`S/(2Y)`

Solution :We know that energy density of the wire
`=1/2` Stress `xx` Strain
`=1/2` Stress `xx("Stress")/Y=(S^(2))/(2Y)`
So the CORRECT CHOICE is (B).
