Test: Compass Surveying & Theodolite - 1

Question 1

In the prismatic compass

Accepted Answer

the magnetic needle and graduated circle do not move with the box

Answer

the magnetic needle.moves with the box

Answer

the fine of the sight does not move with the box

Answer

the graduated circle needle always remains in the N-S direction

Question 2

Local attraction in compass surveying may exist due to

Accepted Answer

presence of magnetic substances near the instrument

Answer

incorrect levelling of the magnetic needle

Answer

loss of magnetism of the needle

Answer

friction of the needle at the pivot

Question 3

The horizontal angle between the true meridian and magnetic meridian at a place is called

Accepted Answer

declination

Answer

azimuth

Answer

local attraction

Answer

magnetic bearing

Question 4

A negative declination shows that the magnetic meridian is to the

Accepted Answer

western side of the true meridian

Answer

eastern side of the true meridian

Answer

southern side of the true meridian

Answer

none of the above

Question 5

If the lower clamp screw is tightened and upper clamp screw is loosened, the theodolite may be rotated

Accepted Answer

on its inner spindle with a relative motion between the vernier and the graduated scale of lower plate

Answer

on its outer spindle with a relative motion between the vernier and graduated scale of lower plate

Answer

on its outer spindle without a relative motion between the vernier and graduated scale of lower plate

Answer

on its inner spindle without a relative motion between the vernier and the graduated scale of lower plate

Question 6

The error due to eccentricity of inner and outer axes can be eliminated by

Accepted Answer

reading both verniers and taking the mean of the two

Answer

taking both face observations and taking the mean of the two

Answer

double sighting

Answer

taking mean of several readings distributed over different'portions of the graduated circle

Question 7

While measuring horizontal angles by the method of repetition with a theodolite, readings are taken on both the verniers. Which one of the following errors will be eliminated by reading both the verniers?

Accepted Answer

Error due to eccentricity of the centres

Answer

Error due to imperfect adjustment of the line of collimation

Answer

Effort due to imperfect adjustment of the horizontal axis

Answer

Error due to imperfect graduations

Question 8

If the quadrantal bearing of a line is N25°W, then the whole circle bearing of the line is
