Challenge Problems
Push your limits with challenges.
Question 1
If a bench mark is at 150m and a back sight reading from the BM is 1.2m, how would you calculate the reduced level of a point with a fore sight reading of 0.8m?
💡 Hint: Use the formula for the Height of Instrument and back calculate.
Question 2
You take a series of staff readings: BS = 1.6m, FS = 0.9m. What is the rise or fall? Following that, if you had another reading: BS = 2.0m, FS = 1.5m, how would you summarize the level changes?
💡 Hint: Make sure you keep track of each change in a journal; it will help in visualizing your data.
