Given information:
Consecutive readings taken with a dumpy level and a 3 m staff on a continuous sloping ground: 0.425, 1.035, 1.950, 2.360, 2.950, 0.750, 1.565, 2.455.
To determine which readings are back sights.
Backsight:
A backsight is a reading taken on a point of known level or elevation, also known as a bench mark, which is used as a reference height for other readings.
Solution:
To determine which readings are back sights, we need to identify the points for which we have a known level or elevation. From the given readings, we can identify that:
- The initial reading of 0.425 is not a backsight as it is the starting point of the survey and there is no known level or elevation for this point.
- The reading of 2.950 is not a backsight as there is no indication that this point is a known level or elevation.
- The reading of 0.750 is a backsight as it is immediately followed by the reading of 1.565, which is higher. This indicates that the point with reading 0.750 is at a lower level or elevation and is a point of known height.
- The final reading of 2.455 is not a backsight as there is no indication that this point is a known level or elevation.
Therefore, the readings that are backsights are:
Option C: 0.425, 0.750.
Hence, option C is the correct answer.
