Question
An engineer has designed a road with a curve of radius 12 m. The material of the road
offers a maximum coefficient of friction of 0.3. What should be the maximum
permissible speed limit on this road?

7 m/s
8 m/s
6 m/s
5 m/s
A car having a weight of 40 kN is moving at a certain speed around the curve. Assuming no lateral pressure between the tire and the pavement, compute for the following if the centrifugal ratio is 0.30.
(a) Compute the force that will tend to pull the car away from the center of the curve.
(b) If the degree of the curve is 4 degrees, determine the maximum speed that the car could move around the curve.
(c) Compute for the embankment angle to be provided for this speed if the skid resistance is 0.12.
A car is traveling at 76 mi/hr down a 3% grade on poor, wet pavement. The car's braking efficiency is 90%. The brakes were applied 320 ft before impacting an object. The car had an antilock braking system, but the system failed 200ft after the brakes had been applied (wheels locked). What speed was the car traveling at just before it impacted the object? (Assume theoretical stopping distance, ignore air resistance, and let Frl=0.015)
