What to enter
| Input | Meaning and units |
|---|---|
| Force magnitude (N) | Enter force magnitude in N; use the same basis as the other measurements. |
| Deflection magnitude (m) | Enter deflection magnitude in m; use the same basis as the other measurements. |
Understanding your result
Read Spring rate (N/m) in the units and model stated on this page. The formula k=force/extension defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
