Energy is stored in a metal wire that is extended elastically. Explain what is meant by extended elastically. Show that the SІ units of energy per unit volume are kg m–1 s–2. For a wire extended elastically, the elastic energy per unit volume X is given by X = Cε2E where C is a constant, ε is the strain of the wire, and E is the Young modulus of the wire. Show that C has no units.
