Forces of Friction at the Wheel-to-Ground Contact in a Turning Vehicle

Forces of friction appear when the wheel of a moving vehicle contacts the ground during. Curvilinear movement of a vehicle is of special interest. The moment of friction appears during the turn in addition to the force of friction. In a turning vehicle the values of friction force and moment of friction depend on each other. The force increases when the moment decreases and vice versa. They are calculated in movement of instant rotation. The force of friction and moment of friction are functions of the coordinates of the instant center of the sliding. It allows to connect forces with the kinematics of movement.
