Which of the following terms are correct for Engineer’s chain?
66 ft long
100 ft long
Surveyor’s chain
None of the above
100 ft long
An Engineer's chain is a standard surveying instrument that is 100 feet long. It is specifically designed for engineering projects and is divided into 100 links, where each link represents 1 foot.
An Engineer's chain is a standard surveying instrument that is 100 feet long. It is specifically designed for engineering projects and is divided into 100 links, where each link represents 1 foot.
L=100 ft — Total length of the Engineer's chain
l=NL=100100=1 ft — Length of a single link
The chain functions as a physical distance measuring tool. Because it is 100 feet long with 100 links, it simplifies decimal-based engineering calculations compared to the 66-foot Gunter's chain, which is subdivided into links based on furlongs and chains.
The Engineer's chain is 100 feet long.
It consists of exactly 100 links.
Each individual link measures 1 foot in length.
It is primarily used in civil engineering works like railways, roads, and bridges.
Calculation is easier due to decimal system (1 foot per link).
Direct compatibility with decimal surveying measurements.
Heavier and bulkier than modern tapes.
Prone to errors due to stretching, temperature, and wear of ring joints.
Railway and road construction surveys.
Large scale engineering layout works.
| Feature | Engineer's Chain | Gunter's Chain |
|---|---|---|
Chain Type | 100 ft | 66 ft |
Gunter's chain (Surveyor's chain) is 66 feet long and divided into 100 links.
Revenue chain is 33 feet long and divided into 16 links.
B is correct — The Engineer's chain is standardly defined as 100 feet in length, subdivided into 100 individual 1-foot links.
Remember: Engineer's = 100ft (Decimal), Gunter's = 66ft (Acreage/Furlong-based), Revenue = 33ft (Cadastral/Land measurement).
