Question

explain stress versus strain graph for a metallic wire when streched up to the breaking point​

Answer 1

The stress-strain graph for a metal wire is given in figure, upto the point B, the wire returns to its original state O along the curve BAO, when it is gradually unloaded. Point E corresponds to the fracture point of the wire.

Answer 2

The stress graph against the strain of metallic wire when stretched to the point of fracture says that is:

The Stress vs Strain steel cable graph states:

• From stress and strain curve.

• The OA line is a limited range, which means that the pressure is directly proportional to the weight.
• It is a region in a state of depression that obeys Hooke's Law.
• To this end, the scale of stress and stress gives us a consistent balance known as the young’s modulus.
• The OA point on the graph is called the boundary.
