    What is the Radius of Curvature for a Banked Curve with Ice on the Road?

    This is my FBD if that clears anything up at all. Ff is my Friction force, yes. I don't know Fn independent of Ff because there are three forces in the y direction.

    What is the Radius of Curvature for a Banked Curve with Ice on the Road?

    @mfb I did solve for theta and got the right answer, 6.842773413 however I'm not sure on how to find r. Is my formula correct? What is the next step I need to take, in order to get read of my Forces?

    What is the Radius of Curvature for a Banked Curve with Ice on the Road?

    Homework Statement A civil engineer is asked to design a curved section of roadway that meets the following conditions: With ice on the road, when the coefficient of static friction between the road and rubber is 0.12, a car at rest must not slide into the ditch and a car traveling less than 70...
