| Q.34 | A tacheometer was set up at a station P and observations were taken on a staff held at Q, the vertical circle reading being zero. The readings corresponding to the three stadia hairs are 1.9 m, 1.6 m, and 1.3 m respectively. The reading (middle cross-hair with vertical circle reading zero) from P to staff held vertically at a Bench mark of elevation +100.0 m is 2.5 m. The horizontal distance PQ and the elevation of point Q are respectively : ( Assume multiplication constant as 100 and additive constant as zero for the tacheometer ) | |
