A highway curve with a radius of 150 meters is banked so that there is no lateral pressure (friction) on the wheels of a car at a speed of 50 km/hr. A car weighing 16.50 KN with tread G = 1.50 meters and height h = 0.70 meters travels around the curve at 100 km/hr. What is the safe angle of inclination of the banked highway curve

The following table shows the stations and ordinates for a mass diagram. The free-haul distance is 600 ft. Overhaul cost is $12 per station yard. (a) Use the method of moments to compute the additional cost that must be paid to the contractor. (b) Sketch the ground profile if the finished grade of this roadway section is level (0 percent).
