(Section A)
(2X10=20)
Q1)
a) differentiate between swinging and plunging operations in theodolite.
b) Write down the statement of Bowditch's rule for balancing a closed traverse.
c) If the degree of curve is 1, then what will be the radius of the curve?
d) Find out the tangent length of a simple circular curve of radius R and angle of deflection Q(fi).
e) if the spacing of cross hairs in a stadia diaphragm of a tacheometer is 1.2mm and the focal length of the object glass is 24cm, then calculate multiplying constant of tacheometer.
f) write an expression for altitude correction in the measurement of base line.
g) what will be the distance to the visible horizon from height of 36m above mean sea level?
h) enumerate the essential componemts of GIS?
i) What is minimum number of sattelites to be connected for proper workin of GPS units?
j) For which purpose stereoscopes are used?
(Section B)
Attempt any four questions from section B
Q2) how you would measure horizontal angle by method or repetition, explain.
Q3) what is transition curve? why it is used?
Q4) Define anallactic lens. For which purpose are they used?
Q5) Calculate the sag corrections for a 30m steel tape under a pull of 100 N in three equal spans of 10m each. Mass of one cubic cm of steel is 7.86gm. Area of cross section of tape= 0.08sq cm.
Q6) What are databases and database management in GIS?
Attempt any two questions from section C
Q7) The tangents to a railway curve meet at an angle of 148 degrees. owing to the position of a building, the curve is chosen that will pass near a point 10m from the point of intersection of the tangents of the bisector of the angle 148 degrees. calculate the suitable radius of the curve.
Q8) What are temporary adjustments in theodolites? describe the various operations involved sequentially.
Q9) write down short notes on the following:
(a) applications of remote sensing in civil engineering
(b) components of GPS.
