Coefficients Of Friction - Roy Mech

Static Coefficient of Friction. The static friction coefficient (μ) between two solid surfaces is defined as the ratio of the tangential force (F) required to produce sliding divided by the normal force between the surfaces (N) μ = F /N . For a horizontal surface the horizontal force (F) to move a solid resting on a flat surface
