Yea your thesis is right.DaveW wrote:Ciro, ringo,
My "thought experiment" was intended to suggest that load transfer would happen when a conventional vehicle was accelerated even if the the suspension was locked & the c.g. was at the ground plane. I'm not completely sure of my logic, hence the post. If true, then an additional transfer component should be added to Ciro's very clear diagram illustrating the "braking" case.
There are much more things who try to turn the car.
Imagine you could hold the tyre with a big clamp (tyre locked) and let the engine run. Then the whole car would want to turn around the tyre. The same thing happens when the tyres stands on the road and can spin. It is similar to a helicopter without rear rotor that starts to rotate around itself.
There is another thing. The engine itself. You can make an easy experiment.
Hold a small electro motor in your hand and start it.
You will notice that even a very small engine without anything mounted to the rotor produces a significant moment who tries to turn your hand.
This has two reasons:
During acceleration of the rotor the rotational inertia has to be overcome.
The force acting on the rotor also acts on the housing and tries to turn it in the other direction.
While the rotor is running on constant speed you don't have to overcome the rotational inertia but there is friction in the bearings so there is still a small amount of torque acting on the housing.
In a F1 car the engine and gearbox are arranged longitudinal so the forces would try to turn the body of the car to the side.
I found a quite good picture in recent race car engineering issue:
