Suppose that a particular highway offramp with a curve radius of 56 m is banked at 10˚ and was originally designed to include a coefficient of static friction of 0.25 between tires and road. If the DoT wants to repost the speed limit so that the curve is correctly banked when including a friction coefficient of only 0.1, what new speed should be posted?

A highway curve of radius 68.0 m is banked at 21.4 degree so that a car traveling at 26.4 m/s (95 km/hr) will utilize both banking and friction to keep it on the curve. Determine the minimum coefficient of static friction between the tires and the road to keep the car on the road at this speed on this curve.
A banked circular highway curve is designed for traffic moving at 62 km/h. The radius of the curve is 214 m. Traffic is moving along the highway at 41 km/h on a rainy day. What is the minimum coefficient of friction between tires and road that will allow cars to take the turn without sliding off the road? (Assume the cars do not have negative lift.)
A curve with a 130 m radius on a level road is banked at the correct angle for a speed of 20 m/s. If an automobile rounds this curve at 30 m/s, what is the minimum coefficient of static friction between tires and road needed to prevent skidding?
