The strain energy per unit volume of a stretched wire is

The stored energy per unit volume of a stretched wire is

strain energy per unit volume is

Strain energy per unit volume of a stretched wire is 5 xx 10^(-3) J/m^3 . If Y = 9 xx 10^10 N/m^2 for the material of the wire , find the tensile stress and strain in the wire .

Potential energy per unit volume of a stretched wire is

Define longitudinal stress and longitudinal strain and show that work done per unit volume of a stretched wire is (1)/(2) "stress" xx "strain".
