Eplenation with Load Transfer on Car Turning/ Acceleration

Click For Summary
SUMMARY

Load transfer during a car's cornering occurs due to the distribution of weight across the tires, influenced by friction forces and normal forces acting on each wheel. When a vehicle turns, the weight shifts towards the outside tires, increasing their normal force and friction, which is essential for maintaining grip. Understanding this dynamic is crucial for optimizing vehicle handling and performance, particularly in racing scenarios. The discussion highlights the importance of considering yaw rotation and its relationship with tire friction and aerodynamics.

PREREQUISITES
  • Understanding of vehicle dynamics and load transfer principles

Hello, I was just hoping if someone could explain to me the reason why load transfer occurs on a car during a turn.

I understand why this is so for braking/accelerating, but not for cornering. Thanks for the help.

I am guessing, correct me if I am wrong, <____[]--|--[]<____
where ___> represent friction forces on tires. the line down the"midle"represents the weight, and of course there are the normal forces on each wheel which i did not draw. I can see by this that only the normal force on the right tire will be the one to oppose the moments (arround the center of mass?) and therefore it has to be pretty big thus also making friction larger on that side.

Also in terms of rotation about the yaw axis how does it happen? If for some reason I get all the friction forces in the tires to be the same with aerodynamics for example will yaw occur or no?
 
I suggest you read Race car suspension Class in this forum to gain insight on what happens when you turn left
