http://www.cecalc.com/References/Design%20Coefficient%20Tables.pdf WebThe coefficient of friction is the ratio between the force slowing something down and the force pushing them together. The larger it is the stronger friction is (and the more the object is slowed down). For example, a person's skates on ice have a small coefficient of friction, but rubber on concrete has a big one.

WebRubber friction is complex, and the coefficient of friction is dependent on the contact geometry, normal load, velocity and temperature, as well as the composition of the rubber. A discussion of the influence of these parameters and some other factors which affect measurement is presented in Annex D.
