Car's weight shift with torque & angular momentum

AI Thread Summary
The discussion centers on understanding how torque and angular momentum affect the weight distribution on a car's tires during turns. When a car turns left, the ground exerts a centripetal force that creates an outward torque, leading to increased downforce on the right-side tires. The right-hand rule is suggested as a method to visualize the relationship between angular momentum and torque, indicating that the direction of the car's lean can be determined by their interaction. Additionally, the stiffness of the suspension on one side can influence how downforce is distributed between the tires, although it does not change the total downforce. Overall, the conversation emphasizes the importance of these forces in determining tire load during vehicle maneuvers.

I am having trouble visualizing which two tires of a car will be pushed down based on the angular momentum and torque of that car. Let's say if its angular momentum is point OUT while its torque is pointing UP in relations to the picture below.

My guess is it's the two right wheels of the picture below.

What I think is the angular momentum wants to go where the torque is in other words "the torque is pushing the angular momentum" you can figure out which way the car is leaning more and figure out which tires of the car carries the most weight at that point in time.

I don't believe so, the link you sent me is even more confusing. For this lecture, all we did was used the right-hand-rule to figure this out, but I am not sure how to do that. I believe it was ANGULAR MOMENTUM x TORQUE gives you the direction of which the car is leaning more. Is that correct?
 
If the car is turning to the left, then the ground exerts a left centripetal force onto the tires, below the center of mass which generates an outwards torque on the car, causing the right side tires to experience more downforce than the left side tires. If the suspension in the roll direction is relatively stiffer at one end then the other, then the stiffer end right side tire will experience more downforce than the less stiffer end right side tire. The sum of the downforce on the right side tires isn't affected by the stiffer end effect, just the distribution of the downforce.
 
Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'
Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...
Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
