Q3) leveling staff setup on a BM of elevation of 89.90 m is observed from point A where the three staff reading are 1.00, 2.37, 3.75 m with a depression angle of 05° 32. Then the staff moved to point B where the three staff reading are(- 0.20, -1.88, -3.57) m with an elevation angle of 04 18. Compute the horizontal distance of B from A and reduced level of stations at B (assume stadia interval factor 100 and the additive constant of the instrument = 30).

To adjust a dumpy level by peg method of adjustment, two points A and B were set up. With the instru- ment at point A, the rod reading at A was 1.623m and the foresight at B was 2.875m. The level is transferred at Band the backsight at B was 1.622m while the rod reading at A was 0.362m. Find the true difference in elevation between A and B. What is the error in the line of sight? Determine the correct rod reading at A that will give the level line of sight with the instrument still at point B.
