Home/Calculators/Structural Mechanics/Frictional Force Frictional Force (Coulomb's Law of Friction)
where:
Ff = Friction Force (N)
μ = Coefficient of firction (Dimensioness)
Fn = Normal force between surfaces (N)
- There is no lubrication or fluid between surfaces.
- Constant surfaces are rigid.
- The coefficient of friction remains constant.
- Normal force is perpendicular.
- There is no significant wear or surface changes.
