What to enter
| Input | Meaning and units |
|---|---|
| Spring rate (N/m) | Enter spring rate in N/m; use the same basis as the other measurements. |
| Signed displacement (m) | Enter signed displacement in m; use the same basis as the other measurements. |
Understanding your result
Read Restoring force (N) in the units and model stated on this page. The formula force=-k*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.
