Unbanked circular motion

  1. Oct 15, 2008 #1
    1. The problem statement, all variables and given/known data
    a highway curve has a radius of 122m. At what angle should the road be banked so that a car travellin at 26.8m/s (60mph) has no tendency to skid sideways on the road? (frictional force is zero)


    2. Relevant equations



    3. The attempt at a solution

    To start of you want to draw the setup as a force diagram at an arbitrary angle (called [itex]\theta[/itex] say), with:
    - The normal reaction
    - The centrifugal force from acceleration in a circle
    - The Weight of the car

    You need to find the angle at which all these forces are balanced. Does this help?
