(b) Describe the methods of balancing the closing error in a closed traverse. 07
Q.3 (a) What are the different methods of theodolite traversing? Describe any one of them
in detail.
07
(b) Derive the expressions for computing horizontal distance and elevation in
trigonometric leveling while base of the object is inaccessible and instrument
stations are in the same vertical plane with the elevated object for the instrument
axis at same level.
07
OR
Q.3 (a) What are different methods of designation of curve? Derive a relationship between
the radius of curve and degree of curve.
07
(b) The Top of church spire O was sighted from two points A and B, being at different
levels and in line with O. The horizontal distance between A and B was 150 m. The
angle of elevation from A and B to O were 35? and 20?, respectively. The angle of
elevation from B to a vane 3.0 m above the foot of the staff held at A, was 15?. The
height of instrument at A and B were 1.750 and 1.500 m, respectively. The Reduced
level of B was 225.225 m. Determine the reduced level of O, and horizontal distance
of the spire from B.
