11. RECIPROCAL LEVELING. In reciprocal leveling across a deep ravine the following sets of rod readings were takent: Instr Near A: BS on A=1.719 m, Average Fs on B=2.578 m Instr Near B: Average BS on A=1.335 m, FS n B=2.176 m Point A is on one side of the ravine and has a known éle- vation of 197.428 m. Point B is on the other side. Deter- mine the elevation of point B.

A differential levelling was conducted from BM1 to BM2 30 km apart. BM1 is at elevation 124. 08 m. The backsight distances averages 150 m in length and the foresight distances averages 100 m. the recorded elevation of BM2 was 274.11 m. If the level used is out of adjustment such that when the bubble was centered the line of sight was inclined 0.003 m upward in distance of 100 m. What would be the corrected elevation of BM2?
3. A differential leveling loop began on BM Rock (elevation=938.08 ft) and closed on BM Tree (elevation=942.47). The plus sight and minus sight distances were kept approximately equal. Readings (in feet) listed in the order taken are 5.8 (+S) on BM Rock, 4.35 (-S) and 3.5 (+S) on TP1, 3.25 (-S) and 6.33 (+S) on BM X, 5.22 (-S) and 4.45 (+S) on TP2, and 3.24 (-S) on BM Tree. Prepare, check, and adjust the notes. (Tabulate your answer)

- In reciprocal leveling across a deep ravine the following sets of rod readings were taken: Instrument set-up near A : BS on A = 1.719m, FS on B = 2.578m Instrument set-up near B : BS on A = 1.335m, FS on B = 2.176m Point A has a known elevation of 197.428m. Determine the elevation of point B.
Engr. Brimrock is conducting a tacheometric survey and wants to know the elevation of station B. The upper and lower stadia readings on the rod held at station B were observed as 3.27 and 1.47, respectively, with the use of theodolite having a stadia interval factor of 99.99. The height of the instrument above station A is 1.37 m and the rod reading is taken at 1.51 m. The vertical angle observed is - 12° 9' and the elevation at station A is 114.09 m above sea level. Determine the elevation at station B above sea level in meters.
