We want to study how a wire behaves when we apply the force continuously on the body. By increasing the stress on the body continuously the corresponding strain is noted down and a graph is drawn between the stress and strain as shown. Here the stress is taken and y-axis and the strain is taken on x-axis.
When we do not apply any force on the body there is no stress and hence there is no strain. With the increase of the stress the strain also increases proportionately up to certain extent and the point up to where it happens is called as elastic limit. Many times this limit is also called asproportionality limit, it meant to say that for many bodies proportionality limit and the elastic limit coincides with each other.
