Note; Attempt all Sections. If require any missing data; then choose suitably.
SECTION A
l. Attempt all parts. Each part carries equal marks. (2 x 7 = 14)
a) How will you identify aridge line and a valley line in a contour map?
b) De?ne local attraction. How will you detect local attraction at a station?
c) What is the difference between accuracy and precision?
d) De?ne a weII?conditioned triangle?
e) What are the principles of surveying? Explain each in brief.
0 What are the various types of meridians?

The instrument is fitted with an agaifytical lens and the constant is 100. comput?? the length ot
PQ and reduce level on The { met level ofP IS 321. 50 m.
b) A 30 m long tape was sf?hdaxdized at 200 C and under a pull of lOOfN The tape was used to
measure the distance AB when the temperature was 45 [?C and the pull was [50 N. The tape was
supported at the ends onlv. Find the corrections per tape length if?the cross section of the tape
was 4 mm? the unit weight of the tape material 18 0. 0786 NW3 and the coeffiment of thermal
expansion ofthe tape material is 11.5 x 10'('/ OC. E= 2 9004390 kN/mz.

of instrument method and ?nd the grad1ent of the line joining the ?rst and the last points.
e) Two straight lines AC and CB intersect at C, at a chainage 0f 86 22?. chains at a de?ection
angle 01620 These lines are to be smoothly connected by a simple curveof radius 12 chains. Find
the tangent length, length of the curve and the chainages 0f the starting and end points of the
curve. F 1nd also the length of the long chord.
