Discussion Overview

The discussion revolves around the aerodynamic forces acting on Formula One racing cars, specifically the concept of downforce and its implications if the car were to be inverted. Participants explore the effects of downforce, lift, and gravitational forces in various scenarios, including theoretical situations where the car is upside down.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant notes that F1 cars generate approximately 2 tonnes of downward force to maintain traction on the track.
  • Another participant suggests that if the car were inverted, the downward force would become upward lift, potentially allowing the car to stick to the ceiling or track.
  • It is proposed that the downward force is likely compensating for any lift generated by the car, with gravity being a critical factor in determining the car's behavior when inverted.
  • A participant mentions that the car would need to be traveling at a certain speed, estimated to be around 100 miles per hour, for these forces to be relevant.
  • One participant claims that the negative lift on an F1 car can exceed three times its weight, suggesting that it could remain adhered to a surface even when inverted.
  • Another participant references the Saleen S7, stating it can theoretically drive upside down at speeds above 121 miles per hour due to its downforce.
  • A claim is made that the Ferrari F50 was the first road car capable of driving upside down, requiring speeds of 200 miles per hour.

Areas of Agreement / Disagreement

Participants express various viewpoints regarding the effects of downforce and lift when a car is inverted, with no clear consensus reached on the specific conditions under which an F1 car could remain adhered to a surface upside down.

Contextual Notes

The discussion includes assumptions about the speeds required for downforce to counteract gravitational forces, but these conditions are not fully resolved or quantified. The relationship between downforce, lift, and speed remains a point of exploration.

I have read that an f1 racing cars fairings produce 2 tonnes of downward force to keep the car stuck to the track. The car weighs 500 kilos so if the track were to be somehow turned upside down while the car was at speed would it fall ?
 
Physics news on Phys.org
Well being that it produces 2tons in the direction downwards... or in the direction of the track, if i understand what you are saying correctly then it would not fall because it produces kind of the opposite of lift, and turning the car's body over in effect would produce lift thereby pushing it to the ceiling or track so to speak. the reason for the 2 tonnes of downward force is probably to compensate for lift that might be created by the car, so it might just be a force offset by something else.


My guess might just be g but you would need to know the lift produced by the car in order to solve for this problem specifically.
 
It'd have to be going at at least 100 miles per hour, although this obviously depends on quite a lot of things.

Another F1 fact, - the coefficient of drag on an F1 car is much, much higher than that of an ordinary road going car.
 
hmmm, i was thinking that when the car is right side up gravity as well as the reverse lift holds the car down.But when its upside down would the downwards force(now upwards) be enough to overcome the gravitational force making the car fall..
 
The Saleen S7, when above 121 miles per hour, it can theoretically drive upsidedown, from all the inverted downforce it creates.
 
The negative lift pushing an F1 car down to the ground can reach three times the force of the actual weight of the car, so yes.
 
I have heard this too, that they could drive upsidedown. The force will push the car against the road. The force is much greater than the weight of the car.

Of course, the moment you approach a turn and have to slow down...
 
ok,thanks for your replies..
 
A Ferrari F50 was the first road car to attain this. It needs to be going at 200Mi/hour to do this.

Wow. That is awsome. I wonder if they tested it out with a driver?
