Situation 1: A two-peg test is used to check whether the ine of sight of the level is in perfect adjustment and the following rod readings are taken, with instrument set up near A, backsight on A is 1.623 m. and foresight reading on B is 2.875 m. With the instrument set up near B, backsight on B is 1.622 and a foresight on A is 0.362 m. a. Find the difference in elevation. b. What should be the correct rod reading on A to give a level line of sight with instrument still set up near B? c. What should be the correct rod reading on B to give a level line of sight with instrument still set up near A?
The differential leveling runs from BM 10 to BM 11 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 BM 11 if the recorded elevation was 140.20m
