What is the value of HI in the 2nd set up? b. Find the elevation of TP5 c. Determine the difference in elevation of TP3 and TP6. d. Determine the elevation of BM2. PROBLEM 2 Explain how is the error cancelled in Reciprocal Levelling. PROBLEM 3 Two points A and B were set up. With the instrument at point A, the rod reading at A was 1.623 m, and the rod reading at B was 2.875 m. The level is transferred at B, the rod reading at A was 0.362, and the rod reading at B was 1.622. a. Find the elevation between A and B. b. What would be the error in the line of sight?
A line of levels was run into a terrain. All of the turning points in the accompanying tabulation were located and readings were taken from an upright leveling rod.

Starting from point A of reduced level 200, the levels were taken to another point B. The reduced level of point B was found to be 198.295. In order to check the leveling work flying levels were taken from point B to point A and the following readings were obtained.

Engr. Madrid performed differential levelling between two benchmarks, she then set up a dumpy level at a convenient location along the general route between BM1, which has an elevation of 463.80 m, and BM2 whose elevation is 457.67 m. A backsight of 1.25 is taken on BM1, then the rodman goes forward to TP1 having a reading of 5.32. The level is moved forward and and was set again to another location. A backsight reading of 9.98 m is taken on the rod held at TP1. At the last set up of the instrument again, a foresight reading of 12.87 was taken at BM2 and a backsight reading of 6.11 m was taken at TP2. Upon checking the levelling notes, the recorder noticed that she missed to take down the foresight reading at TP2. If the survey was correctly done, what could be the foresight reading at TP2? Select the correct response: 6.47 m 4.67 m 5.28 m 5.82 m
