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

V-i graph for a metal wire at temperature is as shown in figure

The stress-strain graphs for two materials are shown in the figure (assume same scale).

The stress-strain graphs for two materials are shown in figure. (Assume same scale).

(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?
