The length of a transition curve is often found from L = v³/(C R). For v = 20 m/s, C = 0.5 m/s³ and R = 400 m, the length is:
सही उत्तर: ग) 40 m
L = 20³/(0.5 × 400) = 8000/200 = 40 m, where C is the rate of change of radial acceleration.

In setting out a circular curve by offsets from chords produced, with full chords of 20 m and a radius of 200 m, the offset for each full chord after the first is:
सही उत्तर: ख) 2.0 m
For full chords, the offset = c²/R = 20²/200 = 2.0 m (the first chord offset is c²/2R).

In a mass haul diagram, a horizontal 'balancing line' cutting the curve at two points indicates that between those points:
सही उत्तर: क) The volumes of cut and fill are equal
Between the two intersections the ordinates are equal, so excavation balances embankment within that length.

The trapezoidal rule for computing areas assumes that the boundary between successive ordinates is:
सही उत्तर: घ) A straight line
Trapezoidal rule assumes straight boundaries between ordinates; Simpson's rule assumes parabolic arcs.

The areas enclosed by the 100 m, 102 m and 104 m contours of a hill are 900 m², 400 m² and 100 m² respectively. By the prismoidal (Simpson's) formula, the volume between the 100 m and 104 m contours is about:
सही उत्तर: ग) 1733 m³
V = (h/3)(A1 + 4A2 + A3) = (2/3)(900 + 1600 + 100) = (2/3)(2600) ≈ 1733 m³.

A contour map is used in water resources projects to delineate the:
सही उत्तर: ख) Catchment area of a river or reservoir
The catchment boundary follows the ridge lines identified from the contours.

-
A ridge line, joining the highest points of the ground and dividing the flow of rainwater to either side, is also called a:
सही उत्तर: क) Watershed line
The ridge line separates drainage, so it is called the watershed; the valley line is called the thalweg.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Where contour lines cross a ridge, they form V or U shapes with the apex pointing:
सही उत्तर: घ) Towards lower ground (downhill)
On a ridge the contours bend outward towards lower ground; in a valley they point uphill.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
The contour lines of a uniformly inclined plane surface are:
सही उत्तर: ग) Straight, parallel and equally spaced
A plane with uniform slope rises equally over equal horizontal distances, giving straight, parallel, evenly spaced contours.

-
In plane tabling, the three-point problem becomes indeterminate when the table station lies:
सही उत्तर: ख) On the circle passing through the three known points
If the station is on the circumscribing (great) circle, all positions on that circle satisfy the observed angles, so no unique solution exists.
