• ### What is the cornering force over the slip angle?

Explanation: The ratio of cornering force to the slip angle is called the cornering power. The cornering power increases due to tire stiffness.

• ### What is side force in Nascar?

Side force is the result of pressure differences between the right and left sides of the body of the car. Body asymmetry in NASCAR vehicles further enhances this effect for left handed turns, with the tail of the vehicle offset toward the right-hand side.
• ### When the slip ratio is o what is happening with the wheel?

2.2 Wheel rotational equation

The slip ratio shows the wheel slip according to the longitudinal velocity of the vehicle and angular velocity of the wheel and 0 ≤ |S| ≤ 1. When ω w = 0 then |S| = 1 and the wheel lock-up will be occurred.
