a vertical angle of -14deg 30min is read to a target of 1.75m above point M. The measured inclined distance is 64.41m and the elevation of point K is 320m above sea level. If the height of the instrument at K is 1.27m, compute the elevation of M
a) In the process of taking a rod reading, one can eliminate parallax mathematically. Parallax is basically a systematic error. True False b) The page check in the field notes is a quality control measure to determine if the user satisfied 1st order class I leveling. True False C) The upper cross hair reading was 8.00 ft. The lower cross hair reading was 6.00 ft. The stadia constant was 100. The horizontal distance from the center of the level to the face of the level rod = 200.0 ft. True False

Q2 In leveling works along a longitudinal section, the natural land levels that were taken at 30 m distances were as follows: 15.27m, 14.98m, 15.02m, 14.84m, 14.75m, 15.30m, 15.00m then, if the longitudinal section of the proposed road begins with the level of its first point with a value less than 6.3 than the level of the natural ground at the last point and ends at the last point of the road with a level greater than the level of the natural ground at the first point by 0.16 so that the slope is uniform at each of its points. Calculate the amount of cutting and burial.
An inverse method of leveling is executed between two existing concrete structures and across a concrete wall located midway between the two structures. All rod readings, as indicated in the sketch, were taken with the rod held upside down. From the data portrayed, if the elevation of A (bottom of the concrete beam of the first structure) is 240.05 m., the elevation of the bottom of the concrete beam of the second structure (indicated as C) should be
