Problem: Trigonometric leveling (base of object is accessible) In order to determine the quantity of filling materials for embankment in a construction site, it is required to determine the difference in elevation (DE) between A and B. The instrument was set up at point A and took a rod reading at point B. Stadia rod B A Horizontal distance AB =55.56m Height of set up @point A= 1.20m Rod reading = 1.80m @ point B Zenith angle to point B = 75°10' 55.56m DE VD 1. Determine the difference in elevation between A and B. a) 13.19m b) 14.11m c) 13.59 d) 12.88m 2. If the finished grade of embankment is sloping from A to B, determine its slope. a) 24.56% b)25.40% d) 15.56% c) 19.88%
