This set of Surveying Multiple Choice Questions & Answers (MCQs) focuses on “Introduction – Accessories For Linear Measurement – 1”.
1. Chains are made up of ______
a) High steel carbon
b) Galvanized mild steel
c) Copper coated iron
d) Iron
View Answer
Explanation: Straight links are bent into rings at the end and joined each other. Only galvanized mild steel is suitable for bending and cost effective.
2. The distance between the centers of two consecutive middle rings is _______
a) Chain length
b) Chain effective length
c) Effective link length
d) Link length
View Answer
Explanation: Number of links is multiplied to the length of link to give chain length. Chain length is the sum of lengths of all links. Link length is always considered between the centers of two consecutive middle rings.
3. The length of the chain is measured from the outside of one handle to the ___________ of the other handle.
a) Inside
b) Outside
c) Centre
d) Before one link
View Answer
Explanation: Length of chain is the end to end distance of complete chain. Chain length is the sum of lengths of all links.
4. Metric chains are generally available in _________
a) 15m
b) 120m
c) 20m
d) 25m
View Answer
Explanation: Metric chains are available in 5, 10, 20 and 30 metres. These are as per Indian Standard Codes, it may vary with country such as America Standard codes etc.
5. Tallies are fixed at every _______ metre length for chains of 10m length.
a) 1
b) 2
c) 2.5
d) 0.5
View Answer
Explanation: Tallies are provided at every one meter in case of 5 and 10 meter chains. These are also provided at every 5 meters in case of 20m and 30m chains.
6. What is provided at every meter in case of 20m and 30m chains?
a) Tallies
b) Pegs
c) Arrows
d) Brass rings
View Answer
Explanation: Tallies are provided at every 5m in case of 20m and 30m chains. Brass rings are used as a mark for required distance. In this case, small brass rings are provided at every meter.
7. The letter ‘m’ marked on the tallies refers to _____
a) Metre
b) Metric chain
c) Non Metric chain
d) Mild steel
View Answer
Explanation: The tallies used for marking distances in the metric chains are marked with the letter ‘m’ in order to distinguish them from non-metric chains.
8. Length of each link in metric chain is ________
a) 1m
b) 2m
c) 0.5m
d) 0.1m
View Answer
Explanation: 5m, 10m and 20m length chains have 5, 10 and 20 links respectively. These are as per Indian Standard Codes, it may vary with a country such as America Standard codes etc.
9. Length of Gunter’s chain is ______
a) 10ft
b) 33ft
c) 66ft
d) 100ft
View Answer
Explanation: Gunter’s chains are used to measure lengths or distances in fields. Gunter’s chain is 66ft long and was originally adopted for convenience in land measurement since 10 sq chains are equal to 1 acre.
10. Length of each link in Gunter’s chain is ______
a) 7.92 ft
b) 0.6 inch
c) 7.92 inch
d) 0.6 m
View Answer
Explanation: 0.6ft or 7.92 inch is the length of each link in the case of Gunter’s chain. Length of Gunter’s chain is always considered in ft. The total length of Gunter’s chain is 66ft.
11. One furlong is equal to ________ Gunter’s chains.
a) 1
b) 10
c) 66
d) 80
View Answer
Explanation: One furlong is equal to 660 ft. Gunter’s chain length is 66ft. Therefore one furlong is equal to 10 Gunter’s chains.
12. How many numbers of links in the case of Gunter’s chain?
a) 66
b) 100
c) 50
d) 80
View Answer
Explanation: Each link length is 0.6ft and chain length is 66ft. Therefore 100 links of each o.6ft make one Gunter’s chain.
13. One mile is equal to _______ Gunter’s chains.
a) 10
b) 66
c) 80
d) 79
View Answer
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.
14. Length of engineer’s chain _______
a) 66ft
b) 100ft
c) 66m
d) 100m
View Answer
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.
15. How many number of links are there in engineer’s chain?
a) 10
b) 100
c) 50
d) 66
View Answer
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.
