- In surveying of differential leveling runs from BM10 to BM11 at a distance of 7.5km. It was observed that the leveling rod was inclined 6º from the vertical every time the backsight is taken. The average BS reading is 3.15m and the average length per set-up is 300m. Determine the error every 300-m set-up and the correct elevation of BM11 if the recorded elevation was 140.20mA line of levels is run from BM1 to BM2, which is 12 km long. Elevation of BM1 was found out to be 100 m and that of BM2 is 125.382 m. Average backsight and foresight distance were 150 m and 100 m respectively. a) (Situation 1) If during the leveling process the line of sight is inclined downward by 0.004 m in a distance of 10 m, what would be the corrected elevation of BM2?A line of levels is run from BM1 to BM2, which is 12 km long. Elevation of BM1 was found out to be 100 m, and that of BM2 is 125.382 m. Average backsight and foresight distance were 150 m and 100 m, respectively. If during the leveling process, the line of sight is inclined downward by 0.004 m in a distance of 10 m, what would be the corrected elevation of BM2?
- In the two-peg test of a dummy level, the following observations are taken. *INserted Photo* Point M is equidistance from both A and B, while P is 2.50m away from B along the extension of line AB and 90 meters from B. Requirements: Determine the true difference in elevation between point A and B. Answer: ____________ With the level still set up at P, determine the rod reading on A and B to which the line of sight should be adjusted. Answer: ____________For all the computed values with decimals, use four (4) digits after the decimal. Differential leveling runs from BM10 to BM11 at a distance of 7.5 km. It was observed that the leveling rod was inclined 6° from the vertical every time the backsight is taken. The average BS reading is 3.15m and the average length per set-up is 300m.
