Document Content and Description Below

PLATE 1. The following tacheometric observation were made on two points P and Q from station A. Station A is located between P and Q The height of the tacheometer at A above the ground was 1.55 m. ... Elevation of A is 75.5000 m. The stadia interval factor K is 100 and the stadia constant C is 0. Staff at Staff Reading Upper Middle Lower P -5012’ 1.388 0.978 0.610 Q +27035’ 1.604 1.286 0.997 a. Determine the elevation of Q Ans. 100.676 m b. Determine the elevation of P. Ans. 69.050 c. Determine the horizontal distance between P and Q. 2. Two hills B and C have elevations of 590 and 780 m respectively. Hill A which has an elevation of 676m is in between B and C. A is located 18 km from B and 15km from C. Determine the clearance or obstruction of the line of sight if an observer is in B so that C will be visible from B. Use hcr= 0.0675k2 Ans. 0.59 obstruction 3. A man is standing at the top of a building. The height of the building is 30m from the ground. The man’s eye is 1.5 from his foot. How far can he see? Use hcr= 0.0675k2. Ans. 21.602km 4. To make peg adjustment, the following notes were taken. Instrument set up midway between A and B Instrument near B Rod Reading on A 1.520 1.683 Rod Reading on B 1.395 1.490 a. Compute the difference in elevation. https://www.coursehero.com/file/56802796/PLATE-NO-7pdf/ This study resource was shar [Show More]
