Coefficient of Friction About Tribology
Thedynamic(or kinetic)coefficient of frictionis defined as the ratio of the friction force during sliding to the applied normal load. Frequently, the static frictioncoefficientis larger than the kinetic. Friction also can be classified into dry and lubricated. Historically, lubrication was used to decrease overall frictioncoefficient…
