ANSWER KEY:PROBLEM 5.11D=150.7275m∆h=33.8483mNOTE:Here is problem 5.10. A calibration was made to evaluate the constant of a transit with a focusing interval telescope. The transit was set to the end of line with a distance of 100m and at the other end, a staff was set with a stadia interval of 0.978m. Calculate the missing constant of the transit. Problem 5.11A survey party conducted a stadia surveying operation with the use of the same transitin Problem 5.10. The upper and lower stadia hair reading on a staff held at station Awere observed as 2.28m and 0.73m, respectively. The height of the instrument abovestation is 1.15m and the rod reading is taken at 1.50m. If the vertical angle observedis 12°47', determine the horizontal and vertical distance between the two stations.

ANSWER KEY:
PROBLEM 5.11
D=150.7275m
∆h=33.8483m

NOTE:
Here is problem 5.10. A calibration was made to evaluate the constant of a transit with a focusing interval telescope. The transit was set to the end of line with a distance of 100m and at the other end, a staff was set with a stadia interval of 0.978m. Calculate the missing constant of the transit.

Problem 5.11
A survey party conducted a stadia surveying operation with the use of the same transit
in Problem 5.10. The upper and lower stadia hair reading on a staff held at station A
were observed as 2.28m and 0.73m, respectively. The height of the instrument above
station is 1.15m and the rod reading is taken at 1.50m. If the vertical angle observed
is 12°47', determine the horizontal and vertical distance between the two stations.
