COMPARISON OF WHEEL ROLLING FRICTION AND WHEEL SLIPPING FRICTION IN MECHANIC LECTURES
Abstract
The question about values of friction forces affecting the driving and driven automobile wheels is considered in this article. These forces are usually named forces of road grip. Different movement regimes are considered corresponding as maximum friction values when there is slipping wheels and also minimal friction values. The calculation expressions are derived to define and compare these values. Also wheel rolling of a car is in consideration. Road grip forces estimations are done to show how many times load carrying with the help of a car is easier than to drag this load.
