A roadway is designed for traffic moving at a speed of 20 m/s. A curved section of the roadway is a circular arc of 760 m radius. The roadway is banked - so that a vehicle can go around the curve - with lateral friction forces equal to zero. The angle at which the roadway is banked is closest to:
A) 3 degrees
B) 1 degree
C) -1 degrees
D) 5 degrees
E) -3 degrees

A roadway for stunt drivers is designed for racecars moving at a speed of 34 m/s. A curved section of the roadway is a circular arc of 236 m radius. The roadway is banked so that a vehicle can go around the curve with the friction force from the road equal to zero. At what angle is the roadway banked? (Give answer to the nearest deg)

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...

The curved section of a horizontal highway is a circular unbanked areof radius 760 m. If the coefficient of statiefriction between this roadway and typical tires is 0.40m, what would be the maximum safe driving speed for this horizontal curved section of highway? When a car goes around a banked circular curve at the proper speed for the banking angle, what force cause it to follow the circular path? gravity the...

A vehicle is moving on a curve on a highway with a with a design speed of 50 mph. The curve has a superelevation with an angle of 3.5 degree with the horizon. The lateral coefficient of friction is equal to 0.22. Determine the minimum design curve radius to keep the vehicle on the highway.

A car is travelling at a flat circular track of radius 25 m and tries to go around at 40 m/sec. a) What should the coefficient of static friction be so the car won’t skid? b) Assume the same car is now travelling at a banked circular track at angle 25o , r=25 m and with same speed. What’s the value of the coefficient of static friction in order for the car not to slide down? c) What would the...

A section of a high speed test track is circular with a radius
of curvature R = 1700 m.
At what angle of θ should the track be inclined so that a car
traveling at 77.0 m/s (172 mph) would keep moving in a circle if
there is oil on that section of the track, i.e., it would not slip
sideways even with zero friction on that section. (Hint: The car's
vertical acceleration is zero.)
