Question
PROBLEM 1 +From the given data of differential levelling shown. STA BS FS BM1 1.256 TP1 1.116 1.886 TP2 1.228 1.527 ТРЗ 1.189 2.246 ТР4 1.070 2.017 TP5 1.831 2.656 ТР6 1.489 2.723 BM2 2.548 The elevation of BM1 is 98.5 meters. Solve for the following: a. 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?
