    Just replying to move this thread up the page as I believe it deserves to be read over a number of times. Since I am not involved in FSAE I don't write much but read this forum a lot. I have been...

    Mola gives immediate mention of the internal work and papers of M. Olley and J. Bidwell in the preface to his book. So I would say it is a pretty sure bet that he used Olley's materials.

    Mr. Milliken,

    Yes, I have had a copy of Gillespie for years. Mola is much narrower in scope, but each equation, in each section, is derived from the ground up from either Newton's laws or...

    Z,




    I, for one, would find it informative I'm sure. But, as my 'Z binder' is turning into a textbook size, I realize one can only ask for a finite amount of 'free' education. :(

    Z,

    I will take a 10% error over having nothing at all.

    After all, in almost all cases I am interested in the relative size of some effect, not calculating an exact number for the purposes...

    I knew you would respond, correct on every count by the way, BillCobb. I got to thinking about Z's posts on the long wheelbase bus, then the kinematics of a bicycle model on rails that he suggested...

    Crude Kinematics

    Attached (I hope) are a few photos of a very crude example of the kinematics I believe Z was trying to describe on page 10 of this thread.

    I believe the YouTube video, while a gross exaggeration of the variable velocity effect, does show your reference of 'lumpy steering'. I hope that is correct and it does demonstrate why...

    A bad example of posting first and thinking later.
