Yes, you have a good point...and I don't fancy wasting a box of pencils working all that out.
You suggest that I pop out with a Newton meter and a bit of rope and pull a few cars so I have some figures for force required to pull certain weights. How would this then be applied to a formula so I...
I have found a formula for 'Rolling Friction':
F = f x W/R
f= coefficient of ROLLING friction (which is 0.01-0.02 for rubber on concrete)
W=weight of cylinder (car in this case)
R= radius of cylinder
PROBLEM: how does having four 'cylinders' effect this calculation? The equation as it stands...
