Which of the following statement is not correct about loaded spiral spring?
- The extension is proportional to the load applied, provided the elastic limite is not exceeded
- If the elsatic limit is not exceeded, the contraction is proportional to the load removed.
-
Up to the yield limit, extension is no longer proportional to the applied load.
- Beyond the elsatic limit, extension is no longer proportional to the applied load.
- If the string regains its shape or form after deformation, it is said to be elastic.
