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.
