Which of the following statements is incorrect?a)Error due to refracti...
In this question, we are given four statements related to levelling and we need to determine which statement is incorrect. Let's analyze each statement one by one.
a) Error due to refraction may not be completely eliminated by reciprocal levelling:
- This statement is correct. Error due to refraction occurs when light rays passing through the atmosphere bend, causing the line of sight to deviate from its true path. Reciprocal levelling is a technique used to minimize the effect of refraction, but it cannot completely eliminate it.
b) Tilting levels are commonly used for precision work:
- This statement is correct. Tilting levels, also known as automatic levels or dumpy levels, are commonly used in surveying and engineering for precise levelling. They are equipped with a compensator that automatically adjusts for any slight tilt or movement, ensuring accurate measurements.
c) The last reading of levelling is always a foresight:
- This statement is incorrect. In levelling, there are two types of readings - foresight and backsight. Foresight is the reading taken on a point that is at a higher elevation than the instrument, while backsight is the reading taken on a point that is at a lower elevation. The last reading in levelling is always a backsight, not a foresight.
d) All of the above statements are incorrect:
- This statement is incorrect. As discussed above, statement a) and b) are correct. Only statement c) is incorrect.
Therefore, the correct answer is option 'D' - All of the above statements are incorrect.
To summarize:
- Statement a) is correct as error due to refraction may not be completely eliminated by reciprocal levelling.
- Statement b) is correct as tilting levels are commonly used for precision work.
- Statement c) is incorrect as the last reading of levelling is always a backsight, not a foresight.
- Option d) is incorrect as only statement c) is incorrect.
