  Traction (engineering) - Wikipedia, the free encyclopedia
Traction refers to the friction between a drive member and the surface it moves upon, where the friction is used to provide motion.
This is one reason for grooves and siping of automotive tires: most water must be displaced from the contact, but inertial effects limit the speed with which it can be displaced.
Particularly in the context of the finite element method, a traction boundary condition is a portion of the boundary of a body for which forces—tangential, normal, or both—is prescribed.

 Traction Battery - Engineers Edge   (Site not responding. Last check: 2007-10-12)
The major emphasis on traction battery design is the necessity of a high capacity to weight and volume ratio, since the vehicle must also carry its power source.
Traction batteries are frequently deep cycled and require a fast charging rate for use usually within 24 hours.
Traction batteries are usually of the tubular plate design, which performs more favorably during deep cycle operation.

 Engine & fuel engineering - Firing order and traction   (Site not responding. Last check: 2007-10-12)
Engineers who design braking systems seem to think that ABS when properly applied is more effective than standard brakes in that the ABS systems lock and unlock (pulse) the brakes as many as 20 times per second depending on the system providing shorter stopping distances as opposed to being in a partial to complete skid.
The engines with 2 large cylinders require more of energy be stored in a flywheel than a similarly displaced 4 cylinder in order to compress that large volume of air.
Also from what I have read GP engines prior to the big bang firing order had a very savage power delivery (ie a big step in the torque curve) and the big bang firing order an effect of softening the throttle response making the bikes easier (relaitvely) to ride.
