What Is Chain In Civil Engineering
A chain is a surveying instrument used in civil engineering comprised of 100 links of 4mm galvanized mild steel wire. It is used to measure distances, areas, angles, heights and depths between two points or lines.
What is a chain in civil engineering?
In civil engineering, a chain is a measuring instrument formed by 100 links of 4mm galvanized mild steel wire. It is used in chain surveying to calculate measurements, distances, areas, angles, heights, and depths between two points or shapes.
What is chain surveying?
Chain surveying is a civil engineering practice that involves making linear measurements in the field. It is suitable for smaller areas with simple details and follows the principle of chain triangulation, dividing the area to be surveyed into several small triangles.
What is the length of an engineer's chain?
The engineer's chain is a unit of length used in engineering surveys, consisting of 100 links with a length of 1 foot each, making a total length of 100 feet. It is also known as the Ramsden's chain, named after its inventor, Jesse Ramsden. Additionally, there are five other types of chains and tapes used in civil surveying engineering.
What is a chain used for?
A chain is used in surveying to measure horizontal distances. It is made up of straight links of galvanized mild steel wire, with the ends bent into looped hands connected using three oval rings for flexibility. The chain is formulated of mild steel.
Chain survey is a basic surveying method where measurements are taken in the field, while analysis and calculations are carried out in the office. It is most appropriate for small plane areas with minimal details and yields reliable results when conducted meticulously.
What is the difference between Chain Survey and angular survey?
Chain survey only involves linear measurements in the field and subsequent calculations are done in the office, while angular survey measures both linear and angular parameters in the field.
How do you measure a chain survey?
Chain surveying is a method of measuring land using a chain or measuring tape to determine distances and a compass to determine angles. The measurements are then used to plot a survey drawing on paper. This method is also sometimes called chain triangulation because triangulation forms the principle of chain surveying.
What are the disadvantages of chain surveying?
Chain surveying has limitations in built-up and large areas, has potential for errors due to chain position and reading, and is time-consuming.
What is chain surveying in civil engineering?
Chain surveying or linear surveying is a land surveying technique where only linear measurements are made. It involves the use of a chain, tape, and ranging rods, and is not recommended for large areas with many details. Its principles are essential knowledge for civil engineers.
What is a chain of measurement?
A chain is a unit of linear measurement used to survey public lands as prescribed by law. In the rectangular system, all measurements are returned in true horizontal distance in links, chains, and miles. The exception to this rule is measurement in feet for mineral and townsite surveys.
What is the length of an engineering chain?
The engineering chain, which is commonly used in civil engineering surveying, has a length of 100 feet and 100 links, with each link measuring 1 foot in length.
What is the standard method of measurement in civil engineering?
The standard method of measurement in civil engineering is the Civil Engineering Standard Method of Measurement, which is used for the preparation of bills of quantities in civil engineering work.
In civil engineering, a chain is a measuring instrument consisting of 100 links of 4mm galvanized mild steel wire. It is used in surveying to calculate distances, areas, angles, heights, and depths between two points or lines.
What is a chain in surveying?
In surveying, a chain is an instrument composed of connecting links of galvanized mild steel used to measure distances. Each connecting link is usually 20 cm, and the mild steel wire is bent into a ring which is joined together with three small circular or oval rings. Additionally, a tally marker or special joint may be installed to mark distances of 5 meters.
An engineer's chain is a 100 feet long measuring tool that comprises of 100 links, with each link measuring 1 foot in length.
What is the length of an engineer chain?
An engineer chain is a unit of length commonly used in engineering surveys. It is equal to 100 feet and divided into 100 links, with each link measuring 1 foot in length. Additionally, 1 chain is equal to a distance of approximately 20.12 meters.
What is the length of a surveyor's chain?
The surveyor's chain is a length measuring tool that is commonly used in the United States. It is made up of links of 7.92 inches each and is typically 66 feet long. However, some American surveyors use a longer chain, known as the engineer's chain or Ramsden's chain, which is 100 feet long and made up of 100 links.
How long is a 66 foot chain?
The 66-foot chain is divided into 100 links, with each link measuring 7.92 inches in length. It is usually marked off into groups of 10 by brass rings or tags, and a quarter chain of 25 links measures 16 feet 6 inches, which is equivalent to a rod or pole. This information is according to Gunter's chain on Wikipedia.
How long is Gunter's chain?
Gunter's chain is a measuring device invented by Edmund Gunter in the early 17th century, which is exactly 22 yards (about 20 m) long and divided into 100 links. This chain is used to measure the public land systems of the United States and Canada, with an area of 10 square chains equal to one acre.
Chain has various uses such as decorating clothing, acting as a wallet chain or pants accessory, and transferring power on a bicycle through a roller chain.
What is the purpose of a chain?
A chain is a flexible connector made of metal links, used for various purposes such as holding, pulling, hoisting, hauling, conveying, and transmitting power.
What is chain in English?
A chain is a series of linked metal rings or links used for various purposes such as supporting heavy objects, holding things together, or for decorative purposes. It can also refer to a metal restraint attached to a prisoner's arms or legs.
What is a chain made up of?
Chains are composed of a series of links consisting of alternating wide and narrow links. Each link has two side plates held together with rivets and a roller placed on the shoulder of the outer link.
What type of chain is used on bicycles?
Roller chain, which is assembled from pin links and roller links, is used on bicycles and can be adapted to various other needs.
