Northern Technical University Technical College of Kirkuk Surveying Technical Engineering Department Surveying II: Second year Lecturer: Asstant.prof. Dr. Muntadher Aidi Shareef PROBLEMS 1. Two distances of 50 and 80 meters were accurately measured out, and the intercepts on the staff between the outer stadia webs were 0.4% at the former distance and 0.7% at the tatter. Calculate the tacheometric constants. om Tom 2. Two sets of tacheometric readings were taken from an instrument station A, the reduced level of which was 15.05 ft to a staff station B. (a) Instrument P-multiplying constant 100, additive constant 14.4 in., staff held vertical. Sub (b) Instrument Q–multiplying constant 95, additive constant 15.5 in., staff he ld normal to the line of sight. Instrument Vertical angle 30° At To Ht of Instrument Stadia Readings P A B 4.52 2.35/3.31/4.27 4.47 Q What should be the stadia readings with instrument Q A 30° 3. The vertical angles to vanes fixed at 0.5 m and 35 m above the foot of the staff held vertically at a point were - 0° 30' and + 1° 12' respectively. Find the horizontal distance and the reduced level of the point, if the level of the instrument axis is 125.380 meters above datum. 4. The horizontal angle subtended at a theodolite by a subtense bar with vanes 3 m apart is 15' 40'. Compute the horizontal distance between the instrument and the bar. Answers: 1. K=100, C=0.4m 2. 1.95; 2.82; 3.68 3. 101.1 m; 123.998m 4. 658.29m Tacheometry Tutorial 2020-2021
