The graph shows the behaviour of a steel wire in the region for whoch the wire obeys Hooke's law. The graph is a parabola. The variables ` X` and `Y` -axes, respectively can be [ stress `(sigma)`,strain `( epsilon)` and elastic potential energy(U) ]

The graph show the behaviour of a length of wire in the region for which the substance obeys Hooke.s law. P and Q represent.

The stress strain graph for a metal wire is as shown in the figure. In the graph, the region in which Hooke's law is obeyed, the ultimate strength and fracture are represented by

(i) State Hook's law. (ii) Draw a labelled graph of tensile stress against tensile strain for a metal wire upto the breaking point. Shhow on your graph the region in which Hooke's law is obeyed. What is the significance of the area between the graph and the strain axis withing the Hooke's law region?

When a uniform metallic wire is stretched the lateral strain produced in it is beta .if sigma and Y are the Poisson's ratio and Young's modulus for wire, then elastic potential energy density of Wire is
