I know that it's counterintuitive, but the frictional force developed between two surfaces is independent of contact area. It depends only on the coefficient of friction and the force pushing the two surfaces together......... |
Yes BUT.............IF the coefficient of friction and force pushing the two surfaces together was equal for two systems with different size contact patches wouldnt the one with a greater surface area develop a greater braking force?
