A long, thin metal wire is hung vertically from a fixed support. Masses are attached to its lower end. The load at the lower end is raised from zero and then reduced again to zero. The diagram shows the force-extension graph that is obtained. Where on the graph is the elastic limit located?
- Aanywhere between point R and point S
- Bbeyond point S but before point T
- Cexactly at point S
- Dexactly at point T
