MCQ on compass surveying | MCQ on surveying with answers | compass surveying mcq with detailed explanation in Hindi
In this video, I tried to cover all the aspects of Compass surveying in MCQ format which is very important. all the concepts are explained in very simple and easy to understand Hindi Language.
1.The Principle of Compass surveying is
Parallelism
Triangulation
Traversing
Resection
Answer is Traversing
2. Which of the following reference direction is used in Geodetic survey
a. True
b. Magnetic
c. Arbitrary
d. All of the above
answer is a. True
3.Compass surveying is not recommended where
For large area
Undulating and crowded area
Area having many details
Local attraction is suspected
Answer is Local attraction is suspected
4. Which of the following compass can be used without a tripod for observing bearings
a. Trough Compass
b. Prismatic Compass
c. Surveyor Compass
d. None of the above
answer is Prismatic Compass
5. In Surveyor Compass , The bearing observed
a. In WCB System
b. In RB System
c. Can vary from 0 to 90 degree
d. Both b and c
answer is Both b and c
6.When the series of lines which begins and ends at the same point, it is called as
Closed Traverse
Open Traverse
Small Traverse
Large Traverse
Answer is Closed Traverse
7.The Horizontal angle made by the Survey Line with North Pole (Magnetic Meridian) or some reference direction , is called as
Bearing of line
Angle of line
Meridian of line
Fore Bearing of line
Answer Bearing of line
Meridian : Meridian is a direction with respect to which the direction of other survey lines are mentioned.
Types of meridian - 1. True meridian, 2. Magnetic meridian 3. Arbitrary meridian
1. True meridian • It is the reference direction of north pole of earth from a given station point. It is also called geographic meridian. it is constant at a station.
• The angle between the true meridian and a survey line is known as 'true bearing' of the line. It is also known as the 'Azimuth'.
2. Magnetic meridian • It is the reference direction of north pole from magnetic needle. There may be variation in Magnetic bearing. The angle between the magnetic meridian and a survey line is known as 'magnetic bearing or simply 'bearing' of the line.
3. Arbitrary meridian: Sometimes for survey of a small area a convenient direction is assumed as a meridian known as 'arbitrary meridian'. The angle between the arbitrary meridian and a survey line is known as 'arbitrary bearing' of the line.
8. Bearing of a line is the horizontal angle it makes with
a. True meridian
b. Magnetic meridian
c. Arbitrary meridian
d. All of the above
answer is All of the above
9.The magnetic bearing of line measured clockwise from north pole towards the survey line, is called as
Whole Circle Bearing (W.C.B)
Reduced Bearing (R.B)
Meridian of line
Fore Bearing of line
Answer is Whole Circle Bearing (W.C.B)
10.The bearing of line measured in the direction to the progress of survey is called as
Whole Circle Bearing (W.C.B)
Reduced Bearing (R.B)
Fore Bearing (F.B.)
Back Bearing (B.B.)
Answer is Fore Bearing (F.B.)
11. If FB of a line is 0 °, its BB is
a. 90 °
b. 180 °
c. 45 °
d. 0°
answer is 180 °
14. The angle of a Dip at a point on Equator is
a. 90 °
b. 180 °
c. 45 °
d. 0°
answer is 0° at Equator and 90 ° at Poles
15. A Declination of 3degree east means
a. Magnetic North is 3 degree east of true North
b. Magnetic North is 3 degree west of true North
c. True North is 3 degree east of Magnetic North
d. True North is 3 degree west of Magnetic North
answer is Magnetic North is 3 degree east of true North
16. Which one of the following statement is correct
a. Zero is Placed at N end
b. Least count is 20 minutes
c. The Graduations are inverted
d. It Indicates Quadrantal Bearing
answer is The Graduations are inverted
17. Which of the following statement is correct
a. Local Attraction affects included angle
b. The position of E and W are interchanged in Prismatic compass
c. Dip of the Magnetic needle is the angle between magnetic north and true north
d. None of the above.
answer is None of the above.
18. The line joining points of Equal Dip are called as
a. Aclinic Lines
b. Isogonic Lines
c. Agonic Lines
d. Isoclinic Lines
answer is Isoclinic Lines
a. Aclinic Lines= The imaginary Line which is parallel to the Equator and passing through the points where Dip is Zero.
b. Isogonic Lines = These are the lines along which the declination has the same constant value.
c. Agonic Lines = These are the lines along which the the declination is zero.
d. Isoclinic Lines= line joining points of Equal Dip
