Question

The following readings were taken on a uniformly sloping ground: \(0.500m, 1.000m, 1.500m, 2.000m, 1.200m, 1.700m, 2.200m, 2.700m\). The difference in elevation between the first and last station is:

• A. \(3.000m \) (fall)
• B. \(3.000m \) (rise)
• C. \(2.200m \) (fall)
• D. \(2.200m \) (rise)

Hint:

To determine elevation differences in leveling, subtract the first reading from the last. If the value is positive, it is a rise; if negative, it is a fall.

Answer 1

The Correct Option is D

Step 1: Identifying the first and last station readings. The first reading is \(0.500m\), and the last reading is \(2.700m\). 
Step 2: Calculating the difference in elevation. \[ \text{Difference}  = \text{Last reading}  - \text{First reading}  = 2.700m - 0.500m = 2.200m. \] 
Step 3: Determining whether it is a rise or fall. Since the last reading is greater than the first reading, the elevation has increased, indicating a rise.
