Consider below statement with respect to methods used to balance a traverse and identify the correct answer.
Statement A: The transit rule may be employed where angular measurements are less precise than the linear
Statement B: The Bowditch's method assumes that the errors in linear measurements are inversely
proportional to the square root of the length of the surveyed line
The Transit Rule is employed for balancing a traverse when angular measurements are more
precise than linear measurements (often the case in theodolite traversing). Since the
statement asserts that angular measurements are less precise, it is false.
Statement B: Incorrect.
Bowditch's Method (Compass Rule) is based on the assumption that errors in linear
measurements (e₁) are directly proportional to the square root of the length of the line (
)
, while errors in angular measurements are inversely proportional to the square root of the length
. Since the statement claims that 1 Vi linear errors are inversely proportional, it is false.
