A wire of length $L$ and cross-sectional area $A$ is made of a material of Young's modulus $Y$, if the wire is stretched by an amount $x$, the work done is (a) $\frac{Y A x^{2}}{2 L}$ (b) $\frac{Y A x}{2 L^{2}}$ (c) $\frac{Y A x}{2 L}$ (d) $\frac{Y A x^{2}}{L}$
Calculate the work done when a wire of length l and area of cross - section A is made of material of young's Modulus Y is stretched by an amount x?

A wire of length $L,$ Young's modulus $Y$, and cross-sectional area $A$ is stretched elastically by an amount A $L$. By Hooke's law, the restoring force is $-k \Delta L$. (a) Show that $k=Y A / L$. (b) Show that the work done in stretching the wire by an amount $\Delta L$ is $W=\frac{1}{2} Y A(\Delta L)^{2} / L$.
