As you know, banking a highway curve can help keep cars from skidding. Suppose that the...
7. A highway curve with a radius of R metres is banked so that cars moving at v m/s around the curve do not have to rely on friction when taking the turn. IWPS 7. No.4] 7.1 Show (from first principles) that the angle, 6, at which, the road should be banked is given by: 0 arctan 7.2 A particular banked highway curve with a radius of 200 m is designed for traffic moving at 60 km/h. On a rainy...
An engineer must design a curved exit ramp for a highway in such a way that a car, exiting at the posted speed limit of 17.88 m/s (40 mi/hr), does not depend on friction to round the curve without skidding. The radius of the curve is 230 m. At what angle with respect to the horizontal must the curve be banked (in degrees)?
A highway curve of radius 70 m is banked at a 15° angle. At what speed vo can a car take this curve without assistance from friction?
A curve in a highway has radius of curvature 130 m and is banked at 3.4°. The coefficients of friction are μs= 0.28 and μk = 0.15. What is the fastest safe speed to drive this curve? You must take into account the coefficient of friction for this problem. The answer is not 8.70 m/s nor 27.37 m/s. Thank you for your help.
Curved portions of highways are always banked (tilted) to prevent cars from sliding off the highway. A car of mass m moves at a constant speed v around a banked circular track of radius R as shown in the figure. If the frictional force from the track is negligible, what bank angle Ѳ prevents sliding.
highway curves are often banked, so the normal force provides the centripetal force and cars don’t have to rely on friction. After having responded to an emergency call in the middle of a snowstorm, an ambulance is speeding back towards the hospital along a slippery curved road. Your job is to inform the ambulance driver of the maximum speed at which he can travel around this curve without slipping up the bank. You are told that the curve has a...
A concrete highway curve of radius 70.0 m is banked at a 19.0° angle. What is the maximum speed with which a 1900 kg rubber-tired car can take this curve without sliding? (Take the static coefficient of friction of rubber on concrete to be 1.0.)
A concrete highway curve of radius 80.0 m is banked at a 19.0 ∘ angle. Part A What is the maximum speed with which a 1400 kg rubber-tired car can take this curve without sliding? (Take the static coefficient of friction of rubber on concrete to be 1.0.)
A concrete highway curve of radius 70.0 m is banked at an 11 degree angle. What is the maximum speed with which a 1200 kg rubber-tired car can take this curve without sliding? (Take the static coefficient of friction of rubber on concrete to be 1.0.)
A section of U.S. highway with a posted speed limit of 70.0 mph (113 kph) has a curve of radius 1,170 ft (357 m). At what angle should the curve be banked so that cars travelling at the speed limit have no tendency to skid sideways? Bank angle: ______________° What if the road were on Mars? (Martian surface gravity is 3.71 m/s².) Assume the same coefficient of friction for a dusty road on Mars as for a wet road on...
