Coefficient of Friction – About Tribology

The dynamic (or kinetic) coefficient of friction is defined as the ratio of the friction force during sliding to the applied normal load. Frequently, the static friction coefficient is larger than the kinetic. Friction also can be classified into dry and lubricated. Historically, lubrication was used to decrease overall friction coefficient by ...
