Question

4) Explain the behavior of wire under increasing load with the help of diagram​

Answer 1

Answer:

The behaviour of the wire under increasing load can be studied by calculating the stress and strain against each load through a graph.

Suppose a metallic wire of uniform cross-section is suspended from a rigid support. When the load on the other end is gradually increased, the length of the wire goes on increasing.

Answer 2

The behaviour of wire under increasing load can be explained with the help of stress v/s strain graph. If the wire is unloaded at point E, the graph between stress and strain follows the reverse path EPO, then the point E is called elastic limit. The portion between O and E is called elastic region.
