If "L" is the length of the chain , "W" is the weight of the chain and 'T' is the tension , the Sag Correction for the chain line is
If the whole circle bearing is 315°20′, its quadrantal bearing would be
A level when set up 25 m from peg A and 50 m from peg B reads 2.847 on a staff held on A and 3.462 on a staff held on B, keeping bubble at its centre while reading. If the reduced levels of A and B are 283.665 m and 284.295 m respectively, the collimation error per 100 m is
An invar tape, 50 m in length, standardized at 20oC temperature and 10kg pull, is used to measure a baseline. The Correction per tape length, if at the time of measurement the temperature was 30o and the coefficient of linear expansion of the tape was 1x106 per oC , will be
A Rectangular plot of 16km2 in area is shown on a map by a similar rectangular area of 1 cm2 , R.F of the scale to measure a distance of 40km will be
Following observations were taken with a transit fitted with stadia wires.
The line of sight was horizontal and the staff was held vertical.
The tacheometric constants k and C are 100 and 0.4 m, respectively. The horizontal distance between staff and instrument is
Following observations were taken during a reciprocal leveling:
If reduced level of P is 140.815 m, the reduced level of Q is
