Q. In the subtense bar method, the horizontal angle subtended by two targets fixed on a horizontal bar at a known distance apart is measured at instrument station by theodolite.

View solution

Q. The two targets are at a distance s apart, and each at s/2 from the centre, i.e. vertical axis. The horizontal angle α is measured carefully by means of a theodolite. Then what is the value of D in the subtense bar method?
