To calibrate an EDM instrument, distance AC, AB, and BC along a straight line were observed as 90.158 m, 60.025 m, and 30.164 m, respectively. What is the systemmeasurement constant for this equipment? Compute the length of each segment corrected for the constant.

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

An angle is observed repeatedly using the same equipment and procedures. Calculate (a) the angle's most probable value, (b) the standard deviation, and (c) the standard deviation of the mean. 23°30'00", 23°29 40", 23°30ʻ15", 23°29'50"
