To find the lowest level of high voltage elevated cable between two towers using total station, station A with reduced level 25.124 m, was occupied with instrument height 1.4 m, and Point B below the cable was observed with target height 1.6 m, slope distance 295.81 m, if zenith angle of B was 90°15'6" , and then point C on cable was observed with zenith angle 88°42'17" , find reduced level of C (Remote Elevation).
The whole magic of the problem lies in the diagram so observe very carefully
You don't understand? Observe again observe until you are familiar
After drawing the figure next just simple math and geometry.
So the RL of the lowest point on the curve is 33.204m
Any further queries feel free to comment
All the best :)
