An offset is laid out 1° 30′ from its true direction on the field. Find the degree of accuracy with which the offset should be measured so that the maximum displacement of the point on the paper from both sources may be equal?

An offset is laid out 1° 30′ from its true direction on the field. Find the degree of accuracy with which the offset should be measured so that the maximum displacement of the point on the paper from both sources may be equal? Correct Answer 1 in 39

Displacement due to angular error is lsin∆. Displacement due to linear error l/r. Equating both r = 38.20. Hence, the offset should be measured with an accuracy of 1 in 39.
