Difference between Traction and Tractive Force ?

  1. Nov 18, 2006 #1
    Difference between "Traction" and "Tractive Force"?

    I need to know exactly what the difference is between "Traction" and "Tractive Force". The more specific and detailed the better.

    I can find definitions of "Traction" but nothing really on "Tractive Force".

    This is specifically in reference to wheels and road surfaces.

    Back story. I have someone who insists on using (teaching) that everything related to wheels and surfaces is "Tractive Force" and discounts "traction". That I can't find a definition of "Tractive Force" that helps me has had me wondering about this for years.

    Thanks for the help!

    A quick search on google indicated that the term "tractive force" seems to be mostly used in relation to trains...

    Then the free dictionary says something like this: Noun 1. driving wheel - a wheel that drives a motor vehicle (transforms torque into a tractive force)

    at http://www.thefreedictionary.com/driving+wheel

    so I decided to ask the difference between tractive force and traction here.

    So I'm wondering, what is the difference between tractive force and traction?

    (The more detailed the better)
