Talk:Slip (vehicle dynamics)

I realize this article is a stub and needs expanding but I'd like to request some clarifications or expansion:

1)The slip is generally given as a percentage of the difference between the surface speed of the wheel compared to the speed between axis and road surface.

The value of (wr) is not the surface speed of the wheel (or tyre), that would be (w2πr), however the equation is correct based off other documents I have read. Could someone correct the description and provide an explanation of why (wr) is used instead of the more intuitive (w2πr)?

2)The article needs to make a distinction between lateral and longitudinal slip as well as make mention of how slip angle is associated with these two concepts. Given that an equation for longitudinal slip is given, perhaps so should an equation for lateral slip if possible.

3)There should be more details on the mechanics of slip so that all the articles referring to tyre deformation can refer to this page instead of each trying to provide a brief summary of how the action occurs.

4) Given that slip provides a basis for motion on all vehicles using tyres could I request that this article get a little more attention.

Finally thank you to everyone who has contributed to vehicle dynamics articles on wiki, I've learnt a great deal! —Preceding unsigned comment added by 118.92.18.95 (talk) 07:45, 20 October 2010 (UTC)

1. The $\omega r$ is correct, it is the angular velocity of the wheel, which gives the velocity of a point on the wheel surface when multiplied by the radius of the wheel. I don't know about the naming of the terms.
2.  Done Lateral slip is a bit tricky to give a single equation for, as it is related to lots of other stuff than the wheel. I added an equation for the slip angle.
