The vertical angles to vanes fixed at 1 m and 3 m above the foot of the staff held vertically at a station P were – 1o 45′ and + 2o 30′, respectively. Find the horizontal distance and the reduced RL of P if the RL of the instrument axis is 110.00 m?
The horizontal angle subtended at the theodolite station by a subtense bar with vanes 3 m apart is 0o 10 ′40′′. Calculate the horizontal distance between the theodolite and the subtense bar?
A tacheometer is setup at an intermediate point on a traverse course PQ and the following observations are made on a staff held vertical. Staff Station Vertical Angle Staff Intercept Axial Hair Readings P + 9o30′ 2.250 2.105 Q + 6o00′ 2.055 1.975 The constants are 100 and 0. Compute the length PQ and the reduced level of Q. RL of P = 350.50 m.
Stadia readings were taken with a theodolite on a vertical staff with the telescope inclined at an angle of depression of 3o30′. The staff readings were 2.990, 2.055 and 1.120. The reduced level of the staff station is 100.000m, and the height of the instrument is 1.40 m. What is the reduced level of the ground at the instrument? Take constants as 100 and zero.
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?
