Question

1x2= 2
The lengths of lines AC and CB will be
2) A level when set up 25m from peg B reads 2.847m on staff held on A and 3.462m on staff held
on B keeping bubble at its centre while reading. If the reduced levels of A and B are 283.665m
and 284.295 m respectively, what is the collimation error per 100m?
1x2 =2
3) In running fly levels from a B.M. of RL 120.750 the following reading were obtained,
BS
0.850
1.285 1.182 0.965 0.490
FS
0.555
1.150
1.945
1.755
From the last position of the instrument, seven pegs at 10.0 m interval are to be set out on
a uniform descending gradient of 1 in 50. The first peg is to have a RL of 120.00m work out
The staff reading required for setting the tops of pegs on to desired gradient. Enter the
Results and rule out a page of the level book. Carry out the arithmetic checks. 1x4-4
4) ABCD is a traverse. The included angle are measured as angle A=110° angle B=54° and
C=125°, angle D=71°, calculate the bearing of the traverse lines with A as origin and AB line as
arbitrary meridian.
1x4=4
1x4-4
