Hi there, Suppose we had a car going in a circle. We know that the turning angle(angle between the movement direction and the wheel axis) and the friction are connected, because friction determines the centripetal force and it determines the radius of the circle that we make with our car. I need to know the relation(equation) between that angle and the friction. We can split it into 2 cases: 1) the centripetal force is not too large for the maximum friction for given materials to be achieved 2) the centripetal force is too big - the car starts drifting Mostly need the 1), but if someone would be so nice to explain to me the math behind the 2) i would be very grateful. The computer program i'm writing establishes the movement direction as the direction a sitting still driver would face. In 2), this direction isn't movement direction anymore, which would complicate it English is my secondary language, so if you could use symbols instead of their spoken equivalents, that would be great. Thanks in advance!
