Test: Compass Surveying & Theodolite - 2 - Question 1

If fore bearing of a line is S 49°52'E (assuming there is no local attraction), the back bearing of the line will be

Detailed Solution: Question 1

If the fore bearing of a line is given as the quadrantal bearing, then back bearing is numerically equal to the fore bearing. However N changes to S and Exchanges to W and vice versa.

Test: Compass Surveying & Theodolite - 2 - Question 2

If the declination is 5°40'W, which one of the following magnetic bearing would represent the true bearing of S 25°20'E?

Detailed Solution: Question 2

Test: Compass Surveying & Theodolite - 2 - Question 3

The prismatic compass and surveyor’s compass

Test: Compass Surveying & Theodolite - 2 - Question 4

The following bearing were observed while traversing with a compass

Which stations were affected by local attraction?

Detailed Solution: Question 4

As the difference between F.B. and B.B. of line AB is exactly 180°, stations A and B are free from local attraction which is not the case with line CD.
Hence stations C and D are affected by local attraction.

Test: Compass Surveying & Theodolite - 2 - Question 5

The multiplying constant of a theodolite is 

Test: Compass Surveying & Theodolite - 2 - Question 6

Theodolite is an instrument used for

Test: Compass Surveying & Theodolite - 2 - Question 7

Agonic line is the line joining points having

Test: Compass Surveying & Theodolite - 2 - Question 8

Which one of the following is carried out by two theodolite method?

Test: Compass Surveying & Theodolite - 2 - Question 9

If the forebearing of a line AB is 35° and that of line BC 15° then the included angle between the lines is

Detailed Solution: Question 9


BB of AB = FB + 180°
= 35° + 180° = 215° 
∴ included angle between line,
AB and BC = 360° - 215° + 15° = 160°

Test: Compass Surveying & Theodolite - 2 - Question 10

What is the magnetic declination at a place if the magnetic bearing of the sun at noon is 184°

Detailed Solution: Question 10

True bearing
= Magnetic bearing + Declination
∴ 180° = 184° + Declination
or Declination = -4° = 4°W
