-
Ranging a line means:
सही उत्तर: क) Establishing intermediate points on a straight line between its ends
Ranging fixes intermediate points (using ranging rods) so that chaining follows a straight line.

Any staff reading taken between the back sight and the fore sight at a set-up, other than on a change point, is a/an:
सही उत्तर: घ) Intermediate sight
Intermediate sights are readings at points whose RLs are needed, without moving the instrument.

A 3-4-5 method in chain surveying is used to:
सही उत्तर: ख) Set out a right angle with a tape
A triangle with sides in ratio 3:4:5 contains a right angle, allowing perpendicular setting out with a tape.

-
The reduced level (RL) of a point is its height above or below:
सही उत्तर: क) An assumed or established datum, such as mean sea level
RL is the elevation relative to a datum, usually mean sea level.

-
The longest chain line in a chain survey, on which the framework is built, is called the:
सही उत्तर: ख) Base line
The base line is the longest and most important line, laid out on level ground through the area.

-
An obstacle such as a river, which obstructs chaining but not ranging, is crossed in chain surveying by:
सही उत्तर: घ) Constructing similar or right-angled triangles to compute the gap indirectly
When ranging is possible but chaining is not, geometric constructions (perpendiculars, similar triangles) give the inaccessible length.

-
Perpendicular or oblique distances measured from a chain line to locate details are called:
सही उत्तर: क) Offsets
Offsets are lateral measurements from the chain line to objects to fix their position.

-
The slope length of a line is 100 m and the difference in elevation between its ends is 6 m. What is the horizontal distance (using the exact formula)?
सही उत्तर: ग) 99.82 m
Horizontal distance = √(100² − 6²) = √9964 ≈ 99.82 m.

-
The correction for pull applied to a tape when the field pull P exceeds the standard pull P0 is given by (P − P0)L/(AE) and is:
सही उत्तर: ख) Positive
Extra pull stretches the tape, so measured lengths are too short and the pull correction is positive.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Invar tapes are used for very precise measurements such as base lines because they have:
सही उत्तर: क) A very low coefficient of thermal expansion
Invar (nickel–steel alloy) expands very little with temperature, minimising temperature errors.
