Question
In a leveling work, sum of the Back Sight (B.S.) and Fore Sight (F.S.) have been found to be 3.085 m and 5.645 m respectively. If the Reduced Level (R.L.) of the starting station is 100.000 m, the R.L. (in m) of the last station is __________.
Correct answer
97.44 to 97.44
Solution
In leveling, the relationship between the sum of back sights, sum of fore sights, and the change in reduced level is given by the arithmetic check:Given:
m
m
First R.L. = 100.000 mSubstituting the values into the equation:Thus, the R.L. of the last station is 97.44 m.
m
m
First R.L. = 100.000 mSubstituting the values into the equation:Thus, the R.L. of the last station is 97.44 m.
