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
6. A line was measured 5 times with a tape on a windy day with these results: 286.85, 286.96, 286.77, 286.80, and 286.88 ft. Find the mean and standard deviation of a single measurement. Then, the measurement was repeated 15 more times, giving a mean of 286.87 ft and a standard deviation of 0.06 ft. Have there been enough repetitions to assure that the standard error of the mean is less than 0.02 ft?

The stadia readings with horizontal sight on a vertical staff held 50 m from a tacheometer were 1.345 and 1.830 distance between the object glass and the vertical axis of the tacheometer was 16 cm and the focal length of th glass was 25 cm. The stadia interval is
A student surveys line AB in a level ground field by taping. While taping, he used pebbles as markers for every 15m tape length due to the unavailability of the chaining pins. After the taping, he obtained 25 pebbles and a partial distance of 6.345m for the 1st trial and 25 pebbles and a partial distance of 6.310m for the 2nd trial. Determine the distance of line AB and the relative precision of the survey.
