Question
To get the topography of a given area, a transit was set up at point A and sighted points B and C. The distance of points B and C from A are 200 m and 60 m, respectively. The stadia
intervals were determined to be the ff:
Stadia Interval
Rod at B
2.001 m
Rod at C
0.600 m
1. Compute the stadia interval factor.
a. 99.93
b. 89.23
c. 94.12
d. 100.01
2. An additional point D was sighted with a stadia interval of 2.12 m. The vertical angle observed is 422'. If the elevation of the point where the instrument was set up is 100 m.
compute the elevation of point D if the stadia constant is 0.30 m.
a. 176.22 m
b. 125.23 m
c. 151.23 m
d. 116.11 m
3. Compute the horizontal distance from the point where the instrument was set up to point D.
a. 284.11 m
b. 119.73 m
c. 182.33 m
d. 210.92 m
