Measuring horizontal distances on sloping ground by holding the chain horizontally in short lengths and transferring points with a plumb bob is called:
सही उत्तर: घ) Stepping
In stepping, short horizontal steps are measured downhill and each end is transferred to the ground by a plumb bob.

When chaining on a slope of angle θ, the hypotenusal allowance to be added at each chain length of 100 links is:
सही उत्तर: ख) 100 (sec θ − 1) links
So that the horizontal equivalent of the measured length is one full chain, the slope length must be 100 sec θ, i.e. an allowance of 100(sec θ − 1) links.

The engineer's chain is 100 ft long with 100 links, so each link is:
सही उत्तर: क) 1 ft
100 ft ÷ 100 links = 1 ft per link; Gunter's chain links are 0.66 ft (7.92 inches).

On a map of scale 1:5000, an area measures 4 cm². The corresponding ground area is:
सही उत्तर: क) 1 hectare
1 cm = 50 m, so 1 cm² = 2500 m²; 4 cm² = 10,000 m² = 1 hectare.

On a map of RF 1:2500, 1 cm on the map represents a ground distance of:
सही उत्तर: ग) 25 m
1 cm × 2500 = 2500 cm = 25 m.

-
A scale of chords is used mainly for:
सही उत्तर: ख) Measuring or setting out angles on a drawing
A scale of chords is marked with chord lengths corresponding to angles, so angles can be plotted without a protractor.

A vernier has 10 divisions equal to 9 main scale divisions, each main division being 1 mm. The least count is:
सही उत्तर: घ) 0.1 mm
Least count = one main division ÷ number of vernier divisions = 1/10 = 0.1 mm.

-
In a retrograde vernier, n divisions of the vernier are equal to:
सही उत्तर: क) (n + 1) divisions of the main scale
A retrograde vernier is graduated in the opposite direction to the main scale and n vernier divisions equal (n + 1) main scale divisions.
