[00:00:00]Stress-strain curve.

[00:00:03]Stress-strain curve is used to study the behavior of a wire subjected to gradually increasing load.

[00:00:11]A metal wire is suspended from a rigid support and a load is hung at its other end.

[00:00:16]By taking strain on X axis >> [music] >> and stress on Y axis, the behavior of the wire can be explained by drawing a graph.

[00:00:25]First, when load is applied on the wire, OA is a straight line. From O to [music] A, stress is directly proportional to strain. That means the wire obeys Hooke's law.

[00:00:36]>> [music] >> Therefore, point A is called proportional limit.

[00:00:40]Now, if the load on the wire is removed, [music] the object regains its original position.
