Chefs des Zoulous avant 1816#Mnguni A tribometer is an instrument that measures tribological quantities, such as coefficient of friction, friction force, and wear volume, between two surfaces in contact.

The coefficient of friction, µ, when the system is stationary, is determined by increasing the hanging mass until the moment that the resting mass begins to slide.

To determine the kinetic coefficient of friction the hanging mass is increased or decreased until the mass system moves at a constant speed.

In both cases, the coefficient of friction is simplified to the ratio of the two masses:.

The coefficient of friction is determined by the ratio of the frictional force to the loading force on the pin.

Traction can also refer to the maximum tractive force between a body and a surface, as limited by available friction; when this is the case, traction is often expressed as the ratio of the maximum tractive force to the normal force and is termed the coefficient of traction (similar to coefficient of friction).

The left hand side is the maximum frictional force, which equals the coefficient of friction μ multiplied by the normal force.

Lubrication based on the coefficient of friction.

It also has a lower coefficient of friction against ultra-high molecular weight polyethylene (UHMWPE), the typical counterface material used in total joint replacements.

The UTQGS traction test procedure measures a tire's coefficient of friction when it is tested on wet asphalt and concrete surfaces.

The coefficient of friction for the pair, test tire and surface, is then determined as the ratio of the longitudinal and vertical forces.

The UTQGS traction rating procedure specifies that the traction coefficients for asphalt and for concrete are to be calculated using the locked-wheel traction coefficient on the tire, or sliding coefficient of friction.

The coefficient of friction rapidly reaches a maximum value at about 10-20 percent slip, and then declines as the longitudinal slip values increase to 100 percent, which represents a fully locked tire.
