SOME ANSWERS TO THIS QUESTION ARE WRONG. KINDLY DOUBLE-CHECK YOUR ANSWER WITH A CALCULATOR. INCLUDE THE PICTURE OF THE CALCULATOR. DRAW THE INITIAL AND FINAL FBD!! A traverse line AB is being measured by theodolite and subtense bar. At station A, the horizontal axis of the theodolite is 1.48m above the ground mark and the horizontal angle subtended by a 2-meter subtense bar set up at station B is 42’18”. The subtense bar is 1.22 m above the ground mark and the vertical angle measured to it on the theodolite is +13056’. Determine the length of the line AB and the difference in elevation between the two ground station marks.
PLEASE ANSWER WITH COMPLETE SOLUTION. THANK YOU. The horizontal distance between two points, A and B is 420m, and these are established along the same direction from a theodolite station. If the distance of the theodolite to point A is twice its distance to point B, what are the subtended angle read on a subtense bar held at A and B?
In determining the elevation of point A and the distance between two points, A and B, a theodolite is set up at A and the following data are obtained: z= 92°45', stadia interval = 1.311m, hi = 1.28m, and the line of sight at 2.62m on rod. The instruments constants are K=100.5 ad C = 0.305m. The elevation of B is 38.25m. Compute the distance AB and the elevation of point A. *Note: Zenith Angle is the angle from the vertical line (from the point above the observer). Distance AB: in meters Elevation of point A: in meters
A theodolite was set up at station A and its height of set up was taken as 2.22m. A stadia rod held at point B was observed at a rod reading of 3.20m with its line of sight on a horizontal position. The elevation of point A is 305.56m. Determine the elevation at point B. Select the correct response: 305.67m 304.58m 309.34m 307.56m
2. A 1" reading theodolite having a multiplying constant of 100 and an additive constant of 0 was centered and levelled a height of 1.48 m above a point C of reduced level 46.87 m.
