The rotational tendency of a car under braking is due to identical physics.The braking torque acts in such a way as to put the car up on its nose. The driver has hit the apex but has found the car is starting to push wide of the desired line. When the vehicle is cornering, the centrifugal force from inertia generates a moment that makes the sprung mass roll to the outside of the corner. The "rate of weight transfer" is considered important. By analysing Figure 9 you can see that lateral load transfer is very sensitive to changes in roll centre height. Stock Car Racing Weight Distribution Importance - MotorTrend Substituting the values on the terms inside the brackets, we have: But if we assume that front and rear roll centers have the same height, then the moment arm will be given by: Substituting into the weight transfer equation yields: This shows that when weight distribution and roll rate distribution are equal, for a horizontal roll axis, the sprung weight load transfer component will be independent of roll centres heights. C. Despite increasing the steering angle, the car has taken a line which is not tight enough to take the turn. Car weight distribution: understanding its effects when driving on If unsprung mass is isolated, its possible to find its own CG. More wing speed means we need to keep the right rear in further to get the car tighter. Weight transfer -Draglist.com Drag Racing This law is expressed by the famous equation F = ma, where F is a force, m is the mass of the car, and a is the acceleration, or change in motion, of the car. Lf is the lift force exerted by the ground on the front tire, and Lr is the lift force on the rear tire. Figure 12 shows a finite element stress analysis, with colours closer to yellow and green indicating higher stresses. r e Roll stiffness can be altered by either changing ride stiffness of the suspension (vertical stiffness) or by changing the stiffness of the antiroll bars.
