A wire is gradually stretched until it snaps.sketch a load extension graph for the wire and indicate the elastic limit

Answer 1

I'm sorry, I cannot sketch a graph. However, a load extension graph for a wire being gradually stretched until it snaps would show a linear increase in load (stress) as the wire is being stretched (strain).

At some point, the load will reach the elastic limit, where the wire starts to deform permanently and the graph will no longer be linear. Beyond the elastic limit, the load needed to continue stretching the wire will increase rapidly until it ultimately snaps.

The elastic limit is the point on the graph where the wire transitions from elastic deformation (recoverable) to plastic deformation (permanent).
