-
The latitude and departure of a traverse line, giving the coordinates of its end relative to its start, are called:
सही उत्तर: घ) Consecutive coordinates
Consecutive coordinates refer each point to the preceding point; independent coordinates refer all points to a common origin.

Gale's traverse table is used for:
सही उत्तर: क) Systematically computing latitudes, departures and coordinates of a traverse
Gale's table organises traverse computations: bearings, latitudes, departures, corrections and coordinates.

The coordinates of three stations are A(0, 0), B(40, 0) and C(0, 30) in metres. The area of triangle ABC by the coordinate method is:
सही उत्तर: क) 600 m²
Area = ½ |x1(y2 − y3) + x2(y3 − y1) + x3(y1 − y2)| = ½ |0 + 40 × 30 + 0| = 600 m².

A traverse line 100 m long has a whole circle bearing of 150°. Its latitude and departure are:
सही उत्तर: ग) −86.60 m and +50.00 m
Latitude = 100 cos 150° = −86.60 m; departure = 100 sin 150° = +50.00 m.

The measured interior angles of a closed four-sided traverse total 360°02'. If the angles were measured with equal care, the correction to each angle is:
सही उत्तर: ग) −30"
Total error = +2' = 120"; distributed equally among 4 angles gives −30" each.

The sum of the exterior angles of a closed traverse having 5 sides should be:
सही उत्तर: ख) 1260°
Sum of exterior angles = (2n + 4) × 90° = 14 × 90° = 1260°.

A theodolite with its horizontal axis 1.5 m above the ground is set 50 m from the base of a tower on level ground. The angle of elevation to the top is 45°. The height of the tower is:
सही उत्तर: क) 51.5 m
Height above the instrument axis = 50 tan 45° = 50 m; adding the instrument height gives 51.5 m.

If the angle of elevation of a point is 30°, its zenith angle is:
सही उत्तर: ख) 60°
Zenith angle = 90° − angle of elevation = 90° − 30° = 60°.

A straight line is prolonged with a theodolite by 'double sighting' (face left and face right) in order to:
सही उत्तर: ग) Eliminate errors due to the line of collimation and horizontal axis adjustments
The mean of points set with face left and face right lies on the true prolongation, cancelling instrumental errors.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Which theodolite error in horizontal angle measurement is eliminated by taking the mean of face left and face right observations?
सही उत्तर: घ) Error due to the line of collimation not being perpendicular to the horizontal axis
Collimation error changes sign on changing face, so averaging face left and face right cancels it.
