1. The two-peg test is used to determine if the line of sight of the telescope is parallel to the axis of the bubble tube. A tilting level is set up halfway between points A and B and rod reading on both points are 1.969 and 2.161 m respectively. The level is then set up 1.50 m away from A along the extension of line AB and 53.50 from B. Then rod readings on A and B were recorded as 1.554 m and 1.728 m, respectively. Determine if the line of sight is inclined downward or upward and the amount by which the horizontal cross hair should be moved to adjust the line of sight.
A stadia interval of 1.325 m is observed on a stadia rod held over a turning point using an engineer's transit with a stadia interval factor of 98.5 and a stadia constant of 0.300 m. The elevation of the instrument station is 379.246 m and the height of instrument above the station is 1.245 m. If the rod reading is 1.649 m and the vertical angle observed is - 15°17', determine the horizontal, vertical, and inclined distances by exact stadia formulas. Also, determine the difference in elevation between the turning point and the instrument station.
