Vehicle turning

  1. Sep 6, 2009 #1
    Hello, I believe we have seen that when a car is travelling in high speed and wants to make a sharp turn, the outer wheels actually sort of like lift of the ground right? What is the cause of this? I was thinking that it might have something to do with moments about the inner wheels? Its has something to do with the centripetal acceleration and the centre of gravity am i right? I cant seem to link them together:confused:

    I think the _inner_ wheels lift because of the centrifugal force acting at the center of mass is pulling outward.

    I am drawing a picture where I am looking at the vehicle from the rear and the vehicle is curving to the left. The outer wheels act as a pivot and I am computing the torque about this pivot. Centrifugal force acts to the right at the center of mass which gives a clockwise torque . Gravity acts downward which gives a counter-acting counter-clockwise torque.

    Oh so it doesn't have anything to do with the static friction between the tires and the ground?

    Yes. The way I am thinking about it, the only role of friction is to enforce a non-slip pivot.
