Coefficient of friction for rubber
WebThe coefficient of friction is a constant that depends on the two surfaces in contact. This constant changes when motion begins. Since fs > fk, and the normal force ( FN) remains … WebThe friction coefficient of the F128 sample was approximately µ = 0.9 ± 0.1, which is typical for highly viscous silicone materials [44]. Only in the case of the silicone/zinc dust composite (ZD ...

WebTest results from an FHWA-sponsored study (Harwood, 1987) indicate that as little as 0.002 in (0.05 mm) of water on the pavement surface can reduce the coefficient of friction by 20 to 30 percent of the dry coefficient of friction. In some cases, a 0.001-in (0.025-mm) water film can reduce friction significantly. WebCoe˝cient of (sliding) friction is a unit-less number that describes the ratio of the force of friction between two bodies and the force pressing them together. The coe˝cient of (sliding) friction depends on the materials used; for example, steel on ice has a low coe˝cient of friction, while rubber on pavement has a high coe˝cient of friction.
