A car rounds a curve that is banked inward. The radius of curvature
of the road is R = 140 m, the banking angle is θ = 26°, and the
coefficient of static friction is μs = 0.39. Find the minimum speed
that the car can have without slipping.

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?

A truck is taking a curve of radius of 200 m and sees the road sign which says on it “12.0 m/sec”. The coefficient of static friction is 0.3 such that the truck does not slide downwards. Find the angle that this curve has been designed to be. (Hint: from the expression for speed v, which we got in lecture for banked curves with friction, solve for angle θ)

A highway curve has a radius of 130 m. At what angle should the road be banked so that a car traveling at 25.8 m/s has no tendency to skid sideways on the road? [Hint: No tendency to skid means the frictional force is zero.] °

A civil engineer wishes to redesign the curved roadway in the figure in such a way that a car will not have to rely on friction to round the curve without skidding. In other words, a car moving at the designated speed can negotiate the curve even when the road is covered with ice. Such a ramp is usually banked, which means that the roadway is tilted toward the inside of the curve. Suppose the designated speed for the road...

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.
