The graph of the relation between the extension of a spiral spring and the load attached to it when it is gradually loaded up to the elastic limit is a straight line up to the elastic limit, after which the spring undergoes plastic deformation.

The following points should be indicated on the graph:

1. The proportionality limit: This is the point at which the line deviates from being linear.

2. The elastic limit: This is the point beyond which the spring undergoes plastic deformation and does not return to its original shape.

3. The yield point: This is the point at which the spring experiences significant permanent deformation.

4. The ultimate tensile strength: This is the maximum stress that the spring can withstand before breaking.

5. The fracture point: This is the point at which the spring breaks completely.
