b)            Directions are observed from a satellite station 200 m from station C with the following results :

A = 00° 00’ 00”

B = 62° 15’ 24”

C = 280° 20’ 12”

The approximate lengths of AC and BC are 25,200 m and 35,000 m respectively. Calculate the angle ACB.

c)             Prove by least square method, if the observations of a quantity are in correlated and of different weights, the most probable value of the quantity is the weighted arithmetic mean of the observations.

2               Attempt any four parts of the following : 5×4=20

a)             What are different methods of designation of a curve? Derive a relationship between the radius and the degree of curve.

b)            How would you select a suitable peg interval for a circular curve? What do you understand by unit chord and sub-chord?

c)             What is a reverse curve? Give various relationships between various elements of a reverse curve.

d)            Determine the ordinates of the points on a circular curve having a long chord of 100 m and versed sine of 5 m. The ordinates are to be measured from the long chord at an interval of 10m.

e)             What are the basic criteria for the design of a transition curve? Derive an expression for super-elevation. What are the advantages of transition curve?

1) Derive an equation of a vertical curve in term of two gradients and length of the curve.
