Hypothetical question concerning vectors of steering?

AI Thread Summary
In a hypothetical scenario where a car swerves left to avoid an animal, the left side experiences more wear due to increased downforce at the contact patches. At the moment of swerving, load distribution remains similar to when driving straight, but side loads increase shortly after. The wear on tires is influenced by factors such as weight distribution and suspension stiffness, particularly in rear-wheel drive vehicles. If the weight distribution is close to 50/50, the tire on the right side may bear more load initially. Overall, understanding the dynamics of G forces and load factors is crucial for analyzing tire wear during maneuvers.

Hypothetically:
-car is aligned properly
-crown has nothing to do with anything
-the steering wheel is on the Left and you weight generously 200lbs.

If you were to draw vectors and include G forces and everything you can think of for this incidence, what would you conclude?

You are going on a straight path, you see an animal and you quickly swerve to the left, which side would you experience the most wear on?

At the instant of the initiation of the swerve, where is the load L or R?

Cut the car in half.
Left vs. Right side of car experiences most wear?
Would this change on a Rear wheel drive car?

We had this discussion in an auto shop and I am not delighted to hear something that was so conter-intuitive that I'd just had to ask!

Left side of car has a bit more downforce at the contact patches than right side.

Do you mean tire wear? I'm not sure how wear relates to load factors (downforce, side load), squirming at the contact patch, slippage at the contact patch, ...

A the instant of of initiation of the swerve, the load factors are the same as going straight. It takes some small, finite amount of time before the side loads become non-zero.

The L / R distribution of the downforce depends on front / rear weight distribution and stiffness of the suspension. If the front / rear weight distribution is near 50% / 50%, then the right tire at the relatively "stiffest" end gets the most load, and the left tire at the relatively "stiffest" end gets the least load.
 
I figured it out now thanks for clarification =)
 
Thread 'Is there a white hole inside every black hole?'
This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...
