Traction (engineering)

Traction refers to the maximum frictional force that can be produced between surfaces without slipping.

The units of traction are those of force, or if expressed as a coefficient of traction (as with coefficient of friction) a ratio.

Traction

Traction is defined as:<blockquote>..a physical process in which a tangential force is transmitted across an interface between two bodies through dry friction or an intervening fluid film resulting in motion, stoppage or the tranmission of power

The traction produced by a vehicle if expressed as a force is synonymous with tractive effort, or tractive force, and closely related to the term drawbar pull.

Coefficient of traction

The coefficient of traction is defined as the usable force for traction divided by the weight on the running gear (wheels, tracks etc.)Construction Management Fundamentals, Clifford J. Schexnayder, Richard Mayo, McGraw-Hill Professional, 2003, ISBN...
