Formula and methodology
Formula: F = μN.
Resistance scales with grip (μ) and pressing force (N): double either and friction doubles. μ = 0 means a perfectly slick surface.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Coefficient of friction (μ) — 0 (frictionless) to 2 (very grippy).; minimum 0; maximum 2
- Normal force — N; Must be positive.; minimum 1.0E-6; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Coefficient of friction (μ) | 0.4 |
| Normal force | 100 |
Friction force 40 N.
Assumptions and limits
- Dry Coulomb friction; μ between 0 and 2 inclusive.
- Normal force positive and perpendicular to the sliding surface.
