View Full Version : Banked Circular Highway Curve? Find friction

A banked circular highway curve is designed for traffic moving at 65 km/h. The radius of the curve is 230 m. Traffic is moving along the highway at 35 km/h on a rainy day. What is the minimum coefficient of friction between tires and road that will allow cars to negotiate the turn without sliding off the road?

I've figured out an angle which equals close to 20 degrees but from there I have no clue what to do. Any Help?

How did you get the angle ? Did you draw a free body diagram ?

Resolve all the forces along a pair of directions, and use the condition that there should be not resultant force (in either direction), or else the car will slip.

Is 0.104 correct? (assuming it's online). Edit no I don't use AIM. I used to have it until I found out it was attached to Weatherbug and other such annoying malwares.
