Andy his whole line of wheels in one place
http://www.chiefdelphi.com/forums/sh...ad.php?t=50284 'course the KOP wheels were still a surprise to come, but based on the numbers he arrived at I think that using a sliding friction value thats ~90% of the should be reasonable. Sooooo...... If they are 1.0 static then ~.9 for the KOP wheels
Updating my math for the sliding friction...
with skyways...
120*.7*.9 = 75.6 lbs
swap center skyways to traction...
120*.625*1.3*.9+120*.1875*.7*2*.9 = 116.1 lbs
As far as rock from a dropped center wheel goes, with our 1/8 drop across a ~30" wheel base the max rock is ~0.5 degrees. We can see it on concrete, but not carpet... it basically is rockless. C'mon, drop that wheel I know you want too. Everybody's doing it.
BTW... does anybody have a good metrics for describing a drivetrain?
Pushes around 170 lbs (static)
15.62 fps High (analytic)
6.10 fps Low (analytic)
turning moment of 2400+ lbf*in (Is this a good metric for turning? Is current draw better?)
