Coefficient of Friction | Engineering Library

where μ s is the coefficient of static friction and μ k is the coefficient of kinetic friction. The value of μ s is generally higher than the value of μ k for a given combination of materials.. Coefficients of friction between materials are best determined through testing. However, it is possible to find tables in the literature for friction coefficients between various materials.
