A long, narrow 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 lowered again until it returns to zero. The diagram illustrates the force-extension graph obtained. Where on the graph would the elastic limit be located?
- Aanywhere between point R and point S
- Bbeyond point S but before point T
- Cexactly at point S
- Dexactly at point T
