Question

write the name of instruments used in Chain surveying explain with heat sketch​

Answer 1

Answer:

Chains are used to measure horizontal distances. Chains are formed of straight links of galvanized mild steel wire called links. The ends of each link are bent into a loop hand connected together by means of three oval rings which afford flexibility to the chain.

The chain s made of mind steel. The ends of the chin are provided with brass handles for dragging the chain on the ground. the outside of the handle is the zero point or the end point of the chain and the length of the chain measured from the outside of one handle to the outside of the other. The length of a link is the distance between the centers of the two consecutive middle rings.

The length of a link is the distance between the centers of the two consecutive middle rings.

The end links include the handles. Metallic tags are indicators of the chain to facilitate quick reading of fraction of a chain in surveying measurements. Metric survey chains are available in lengths of 20m and 30m. The 20m chain contains 100 links whereas 30m. Chain contains 150 links. One link of both the type of chain measure 20cm.
