Definition

Given two surfaces, the limiting coefficient of static friction between them, denoted \mu_s or \mu_l, is defined as the number such that the static friction between any two bodies with these two surfaces respectively as the surfaces of contact cannot exceed \mu_sN, where N is the normal force between the two bodies.

The notion of limiting coefficient of static friction arises as part of the Coulomb model of friction.
