Answer :
Answer:
The height reading on the rod is 11.26 ft
Explanation:
Given;
Benchmark of the vertical control point, BM = 100 ft
Height of instrument, HI = 100 ft + 9.76 ft = 109.76 ft
Height of stake, H = 98.5 ft
The height reading on the rod is the foresight reading, gotten by subtracting height of stake from height of instrument.
The height reading on the rod = HI - H
The height reading on the rod = 109.76 ft - 98.5 ft
The height reading on the rod = 11.26 ft
Therefore, the height reading on the rod for setting the receiver at an elevation of 98.5' is 11.26 ft
