Copy the questions and answer. Provide necessary drawings / illustrations base on the problems. Problem 1: A -3% grade meets a +5% grade near an underpass. In order to maintain the minimum clearance allowed under the bridge and at the same time introduce a vertical transition curve in the grade line, it is necessary to use a curve that lies 200m on one side of the vertex of the straight grade and 100m on the other. The station of the beginning of the curve (200m side) is 10+ 000 and its elevation is 228m. a.) Determine the elevation at station 10 + 040. b.) If the uphill edge of the underside of the bridge is at station 10+ 220 and at elevation 229.60m, what is the vertical clearance under the bridge at this point? c.)
