Traction (drive)

Rotational forces :
G: weight
N: opposing frictional forces
V: speed of movement

Traction ( Latin trahere , drag 'pull') referred to in any type of vehicles their powered locomotion. In the physical sense, it is a form of tensile force that is converted into rotation when overcoming rolling resistance to move loads. A factor to be calculated in the process of movement is the traction coefficient, a technical quantity, a quotient of the forces used for movement and the load being moved. Achieving a low coefficient of traction is equally important for the maintenance and manufacturing industries of vehicles and accessories as well as for transportation companies .
