Question

(3) Obtain an experssion for strain
energy per unit volume of the
material of a wire.​

Answer 1

Answer:

The expression for strain energy is 1/2 × stress × strain.

The expression for strain energy is 1/2 × stress × strain.Strain energy = U = 0.5 Fl, where f is external force applied to produce an extension 'i. Thus the energy density of a strained wire or the potential energy per unit volume of a stretched wire is derived.

Answer 2

Answer:- The experssion of strain energy is 1/2 stress × string.

String energy = U = 0.5 FI where F is external force applied to produce an extension I, the energy density of a string wire or the potential energy per unit volume of the streched wire is derived.
