1. A theodolite is set up at one end of a level line 150.0 m long. The line is marked by stakes at every 30.0 m and a stadia rod is held at each stake. The stadia intercept at each station of the rod is observed as follows: 0.302, 0.600, 0.899, 1.207, and 1.506 meters, respectively. Compute the stadia interval factor (K) for each distance and also determine the average value of K. Take C = 0.300

1. A theodolite is set up at one end of a level line 150.0 m long. The line is marked by stakes at every 30.0 m and a stadia
rod is held at each stake. The stadia intercept at each station of the rod is observed as follows: 0.302, 0.600, 0.899, 1.207,
and 1.506 meters, respectively. Compute the stadia interval factor (K) for each distance and also determine the average
value of K. Take C = 0.300
2. The following data were obtained by stadia observations: vertical angle = +7°55', upper stadia hair and lower stadia
hair readings are 2.352 m, and 0.885 m, respectively. The stadia interval factor is known to be 101.0 and C is 0.381 m.
The height of instrument above the instrument station (point A) is 1.496 m and the rod reading is taken at 1.589 m.
Determine the following:
a) Horizontal, vertical, and inclined distances by exact stadia formulas.
b) Elevation of the point sighted (point B) if the elevation of point A is 776.545 m.
c) Difference in elevation between the two points.
3. A traverse is being measured by a theodolite and subtense bar. At one station, the theodolite axis is 1.11m
above the ground mark and the horizontal angle subtended by a 2 meter subtense bar placed at the second station
is 42'11". The subtense bar is 1.34m above the ground mark, and the vertical angle measured to it on the
theodolite is -28°33'. Determine the horizontal and vertical distances between the two station marks.
