Frictional coefficant of wheels on the carpet

Not to be picky, which is natural for me as a physics teacher...but the coefficient of friction of any type is related to two objects ... the wheel contact material, "tread" (or any material for that matter) AND the carpet or other surface. Values of mu for the wheel tread materials found on here are, for the most part, experimentally determined based on the
use of the playing field carpet as this second material.

If you do a look up on frictional coefficients in a materials text be careful not to assume that any figure is good for the playing surface. They will give you a good general feel for the coefficient but different materials react differently with different surfaces.

good luck
