Surveying MCQ - Chain Folding, Unfolding, Adjustment, Degree of Accuracy

1. One furlong is equal to ________ Gunter’s chains.
a) 1
b) 10
c) 66
d) 80

Answer: b
Explanation: One furlong is equal to 660 ft. Gunter’s chain length is 66ft. Therefore one furlong is equal to 10 Gunter’s chains.

2. How many numbers of links in the case of Gunter’s chain?
a) 66
b) 100
c) 50
d) 80

Answer: b
Explanation: Each link length is 0.6ft and chain length is 66ft. Therefore 100 links of each 0.6ft make one Gunter’s chain.

3. One mile is equal to _______ Gunter’s chains.
a) 10
b) 66
c) 80
d) 79

Answer: c
Explanation: 80 Gunter’s chains = 1 mile. Length of each Gunter’s chain is 66ft. 5280 ft is approximately equal to one mile. Therefore, to measure one mile distance 80 Gunter chains are required.

4. Length of engineer’s chain _______
a) 66ft
b) 100ft
c) 66m
d) 100m

Answer: b
Explanation: Length of one link is one ft. Total 100 links forms a chain of length 100ft. Engineer’s chain is always measured in ft.

5. How many number of links are there in engineer’s chain?
a) 10
b) 100
c) 50
d) 66

Answer: b
Explanation: Length of each link is one ft. Length of the engineer’s chain is 100ft. Therefore, dividing total length of chain by length of each chain gives the total number of links.

6. Process of fixing or establishing intermediate points is known as _______
a) Chaining
b) Ranging
c) Contouring
d) Levelling

Answer: b
Explanation: If the length of the survey line exceeds the length of the chain, some intermediate points will have to establish in line with two terminal points before chaining is started. The process of fixing or establishing such intermediate points is known as Ranging.

7. Direct ranging is done when the two ends of the survey lines are _______
a) Invisible
b) Intervisible
c) Visible from a particular point
d) Faraway from each other

Answer: b
Explanation: Direct ranging is the type of ranging in which the two points for ranging are chosen in such a way that they are intervisible. If two points chosen are not intervisible then indirect ranging is done.

8. If rapid sweep with right hand signaled by surveyor then action by the assistant is _______
a) Move slowly to the right
b) Move considerably to the right
c) Continue to move to the right
d) Plumb the rod to the right

Answer: b
Explanation: Rapid sweep by the surveyor implies move considerably. Right hand of the surveyor implies that the assistant has to move right side.

9. If right hand extended by surveyor then action by the assistant should be ______
a) Move slowly to the right
b) Move considerably to the right
c) Continue to move to the right
d) Plumb the rod to the right

Answer: c
Explanation: Extended hand of the surveyor implies that the assistant should continue to move. Right hand of the surveyor implies that the assistant has to move right side.

10. Right arm up and moved to the right by the surveyor then the action of assistant should be ________
a) Move slowly to the right
b) Move considerably to the righ
c) Continue to move to the right
d) Plumb the rod to the right

Answer: d
Explanation: Arm up and moved by the surveyor implies that the assistant has to plumb the rod. Right hand of the surveyor implies that assistant has to move right side.
