Tire friction
WebThe force that resists the motion of a body rolling on a surface is called the rolling resistance or the rolling friction. The rolling resistance can be expressed by the generic equation Fr = c W (1) where Fr = rolling … WebThe tire friction marks observed on the roadway in Photograph 3 are characteristic of yaw marks. The heaviest, more pronounced and apparent marks are those from the leading side tires, because the weight shifts toward the tires on the leading side of the vehicle in yaw. In this case, the right front and rear tires leave heavy rubber transfer marks.
