Friction Calculation: Formula for Determining Wheel-Surface Friction

961008 · Feb 10, 2016

How can we calculate the friction between the wheels and the surface in contact? I know that big wheels will have a greater friction, but what is the formula to calculate it?

What source tells you that big wheels have a greater friction? And what dimension of "big" do you have in mind -- width, diameter, size of contact patch, weight?

The friction I refer to is the friction per revolution of the wheel. The "big" refers to the diameter of the wheels, with the same width.

Friction is normally measured in units of force. How does that make sense in describing friction "per revolution"?

Do you mean friction or rolling resistance?
