Homework Help: Help with a vehicle roll problem

  1. Sep 5, 2006 #1
    I want to calculate the roll of a car going around a turn that is bank 24 degrees at a velocity of 160mph and a track width of 50 inches. TO be honest I am not sure where to start with the data I am given. It would seem to be a simple dynamics problem

    I beleive you need to know the radius of the turn to calculate the centripetal force. If you know that, then you can figure everything else out.

    I thought something about that, but I dont have a radius. The professor did make up this problem, so maybe he forgot to tell us all the info.

    Without the radius, you cannot solve the problem. The "track width" seems to be an additional part of the radius. If the radius is the distance from the center of the course to the inner edge of the track, then the track width multiplied by the cosine of the banking angle will give the extra component of the radius which is required for further calculations.

    That, or the professor was not specific in what the "track width" is.

    what do you mean by
    "I want to calculate the roll of a car"?
    is it the net acceleration you want? or all the forces acting on it? or?...

    sorry im not following you.
