Physics of Fiction

[nwagers]

I got into a dispute with a team member over the connection of surface area and the force of friction. Basically he said that using two wheels instead of one (like on big trucks) would give the robot better traction. Other than the trivial weight distribution of the extra wheel, I said that it had absolutely no impact based on the equation for Friction (Friction = coeff * force normal). We both agreed instead of arguing that we would accept whatever response is given from this message.... So any comments on this one?
