Thank-you bhart,
I think that that is indeed how we view it!
I see it from the Design point of view that I must spec. the right size of tyre to 'put off' the time when the bifurcation of traction vs load line becomes a serious concern.
Yes a lot of the old thinking is constantly being raked...
Hmmmm...
I asked if he meant cogging difference at the start of the slope and that was not it.
I remember back in the late 70's some tests done [admittedly Static friction] on Austin Mini wheels [10in. diameter] and tyres where a reading was taken for traction vs load using a simple 'pull...
I equated it to simple ground pressure, I said if the ideal ground pressure for a given tyre is 'x' then upto that point the tyre will behave in a linear fashion upto a point then after that any weight added will not give an equal return in traction.
If the tyre is is loaded with 0.5 'x' then...
Except to say that this is not a cornering situation.
Straight line stuff, we both agree that the across axle weight shift will lessen overall traction and that this loss will occur.
The point came about due to me saying that there was a way to work out an ideal width of tyre for the weight of...
Cheers Greg.
The graph is a traction graph as you say, I did say the same thing as yourself in that at the start and even along that line there will be some vagueness simply due to inherent testing tolerances, interstices etc, but he still maintains that the tyre is always losing grip as soon...
Hi!
Could someone here tell me if I have to eat humble pie or not?
I have become embroiled in a fairly heated 'debate' about 'grip and slip'.
My view is simply that a tyre has a certain level of 'grip' by which I mean it has a quota of Adherence and Conformity that ensures you have traction...
