The ideal transition curve, in which the radius is inversely proportional to the length travelled, is the:
सही उत्तर: क) Clothoid (Euler spiral)
In a clothoid the curvature increases linearly with length, i.e. radius is inversely proportional to length.

The radius of a 4° curve, with degree of curve defined on a 30 m arc, is approximately:
सही उत्तर: ख) 429.7 m
R = 1718.9/D = 1718.9/4 ≈ 429.7 m for a 30 m standard length.

The length of a simple circular curve of radius 200 m with a deflection angle of 60° is approximately:
सही उत्तर: ग) 209.4 m
Length = πRΔ/180 = π × 200 × 60/180 ≈ 209.4 m.

For a simple circular curve of radius 300 m and deflection angle 40°, the tangent length is approximately:
सही उत्तर: घ) 109.2 m
Tangent length = R tan(Δ/2) = 300 × tan 20° ≈ 109.2 m.

The function of an anallactic lens in a tacheometer is to:
सही उत्तर: क) Make the additive constant zero
The anallactic lens makes the additive constant zero so that D = kS directly.

-
In stadia tacheometry with multiplying constant 100 and an anallactic lens, the staff intercept on a horizontal sight is 1.25 m. The horizontal distance is:
सही उत्तर: ख) 125 m
With an anallactic lens the additive constant is zero, so D = kS = 100 × 1.25 = 125 m.

Lehmann's method in plane tabling is used to solve the:
सही उत्तर: ग) Three-point problem
Lehmann's (trial and error) method is a standard solution of the three-point problem.

-
In plane tabling, the method of locating the plane table station by sighting to already plotted known points is called:
सही उत्तर: घ) Resection
Resection fixes the position of the occupied station on the sheet from known plotted points.

Bowditch's (compass) rule for balancing a traverse distributes the closing error in proportion to the:
सही उत्तर: क) Length of each line
Bowditch's rule assumes angular and linear errors are equally accurate and corrects in proportion to line length.
