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 obtained. At what point on the graph would the elastic limit be located?
- Aanywhere between point R and point S
- Bjust beyond point S
- Cexactly at point S
- Dexactly at point T
