Friction Force Calculator (f=μN)
Compute friction via f = μ·N: enter the coefficient and normal force (from direct input, mass or an incline) to get static/kinetic friction.
Key points
Friction Force Calculator (f=μN): Compute friction via f = μ·N: enter the coefficient and normal force (from direct input, mass or an incline) to get static/kinetic friction. Formula: f = μ·N. Enter parameters on the DD-CAT IDE online tool page to get results instantly, with a calculation-model diagram that updates with the inputs. f = μN: friction is proportional to the normal force and independent of contact area; μ is the dimensionless friction coefficient. Static friction is variable (up to a maximum), while kinetic friction is roughly constant and usually smaller than the maximum static friction.
Inputs
f = μ·NCalculation model (updates with parameters)
| Friction force f | 30 N | f = μ·N |
| Normal force N | 100 N | Direct input value |
| If μ is the static coefficient | 30 N | Maximum static friction; sliding begins beyond it |
Engineering notes
- f = μN: friction is proportional to the normal force and independent of contact area; μ is the dimensionless friction coefficient.
- Static friction is variable (up to a maximum), while kinetic friction is roughly constant and usually smaller than the maximum static friction.
- Typical coefficients: lubricated steel–steel ≈ 0.05–0.1, rubber–dry asphalt ≈ 0.7–1.0, ice–steel ≈ 0.03.
