Question

The graph between applied force and change in the length of wire within elastic limit is a.......................

1. straight line with positive slope.
2. straight line with negative slope.
3. curve with positive slope.
4. curve with negative slope.

Solution

(a) straight line with positive slope.

Stress is directly proportional to strain and the elastic limit is

F/Aprop(DeltaL)/L

Since, A and L are constants.

∴ F ∝ ΔL

Thus, the graph between applied force and change in length is a straight line with
a positive slope.

Is there an error in this question or solution?
