1.

(4) inversely proportional to R but directly proportional to vIf S' is stress and Y' is Young's modulus of material of a wire, the energy stored in the wire per unitvolume isAIEEE-2005, 31225,-112Y(4)YS2

Answer»

Energy stored per unit volume,

E = 1/2 * stress * strain

We know that,

E = 1/2* stress * stress/Y = 1/2 .S2/Y
