Subtopic: Measurement of angles and bearings
Question Statement:
In balancing a closed theodolite traverse, Bowditch's rule (compass rule) is applied when:
Options:
(A) Linear measurements and angular measurements are made with equal precision
(B) Angular measurements are far more precise than linear measurements
(C) Only linear measurements are recorded
(D) Traverse has zero closing error
Answer Key:
A
Step-by-Step Solution & Explanation
Bowditch's rule assumes errors in linear measurements are proportional to $\sqrt{l}$ and errors in angular measurements are proportional to $1/\sqrt{l}$, distributing closing error in proportion to line lengths.
