Felt friction coefficient
WebA coefficient of friction is a value that shows the relationship between two objects and the normal reaction between the objects that are involved. It is a value that is sometimes used in physics to find an object's normal force or frictional force when other methods are unavailable..

Webtion [4]. The friction coeƒcient is deÞned as l" F & F 0 (1) where F 0 is the force of compression. For a Þxed direction of compression, the friction force depends on the direction of sliding, and a second order tensor has been used to deÞne the in-plane friction coeƒcient [4]. Anisotropy of friction has been experimentally observed in ... WebCOEFFICIENT OF FRICTION Introduction Friction is the force that resists the sliding of one surface against another.
