A line of three-wire differential levels goes from benchmark Gloria o benchmark Carey. The length of the line was determined to be 199 m. The instrument had a stated compensator accuracy of +0.3". The instrument-rod combination had an estimated reading error of ±1 nm/km. The instrument is found to have an inclined collimation error of 1.0 mm/km, so the sight distances were kept to approximately 50 ± 5 m. If the difference in elevation observed is 15.601 m, what is the stimated error in the final elevation difference?

Problem 8: The following are the results of the measurement of a survey line between two tripod heads, where the tape was allowed to Sag Line AB Slope Length Vertical Angle Temperature Tension 25.510m 6° 00' 20 °C 80 N The Tape weighted 0.25 N/m; had cross sectional Area of 3mm2 and was actually 30.005 m long at the time of measurements. Where the nominal length of the tape is 30.0 m Calculate the corrected horizontal length of the Line AB

PLEASE FIND SOLUTION THAT WILL COME UP WITH THE SAME ANSWER The two-peg test is used to determine if the line of sight of an engineer’s level is in adjustment, and the following rod readings are taken: with instrument set up near A, rod reading on A is 1.623 m, rod reading on B is 2.875 m; with instrument set up near B, rod reading on B is 1.622 m, and rod reading on A is 0.362 m.   i. The correct rod reading on A to give a level line of sight with the instrument still set up near B should be? answer: 0.366 m ii. In order to adjust the line of sight, the horizontal cross hairs should be moved? answer: Upward by 0.004 m
