Hooke's Law states: the extension of a wire is directly proportional to the force applied.
Force (F) = constant (k) x extention (e)
Hooke's law also applys to springs.
- The expension or compression of a spring is proportional to the force applied.
Hooke's law stops working when the load is great enough.
If you increase the load past the elasctic limit, the material will become permanently stretched.
- Metals generally obey Hooke's law up to the limit of proportionality, which is very near the elastic limit.
- Be careful: some materials like rubber only…
