Friction Circle and Racing

Hey everyone. One of my past times was going to the racetrack with the Porsche Club. Driving fast has a lot to do with understanding the physics behind it. Here is a great video explaining the limits of tires while going fast around corners. Just remember to keep it on the on the track and off the streets.

The videos diagram is a little off. Another way to think of this is the next time you have a drink in your car, when you accelerate the liquid would be pressing backwards and when you brake it would slosh to the front. Same goes for turning. Finding the limits of grip while keeping maximum acceleration and grip is what makes fast lap times.

Hope you all enjoyed the video and here is another one of an example of what it looks like while driving on track. This video has the data overlay of the G forces and speeds with the location on track.
