1.A +2 percent grade on an arterial highway intersects with a -1 percent grade at station (535 + 24.24) at an elevation of 300 ft. if the design speed of the highway is 65 mi/h, determine the stations and elevations of the BVC and EVC, the elevation of each 100-ft station, and the high point. Use L= KA.
2.A 300 N force is applied at A as shown. Determine
(a) the moment of the 300 N force about D,
(b) the magnitude and sense of the horizontal force applied at C that creates the same moment about D,
(c) the smallest force applied at C that creates the same moment about D.
