Physical Law
While Hooke's Law is exact only when applied to an ideal spring, it also applies, up to a certain stress, to an actual physical body.
Stress-Strain Diagram
Let the stress on $\BB$ be plotted on the $x$-axis of a graph with the strain caused by the stress plotted against the $y$-axis.
The resulting graph is called a stress-strain diagram.
The above diagram shows a typical graph of stress against strain.
The segment $OA$ represents the region in which Hooke's Law actually applies.
The slope of $OA$ is the modulus of elasticity of the material of which the body is composed.
