1.
An ideal transition curve is
cubic parabola
cubic spiral
clothoid spiral
true spiral.
Explanation:

IRC recommends Spiral or clothoid as the ideal transition curve due to following reasons:

1. It satisfies that rate of change of centrifugal acceleration is constant i.e., Ls.R = constant. Where Ls = length of transition curve R = radius of curve.

2. The calculation and field implementation of spiral curve is simple and easy.

3. It enhances aesthetics also.

2.
Pantagraph is used for
measuring distances
measuring areas
enlarging or reducing plans
setting out right angles
Explanation:
No answer description is available. Let's discuss.

3.
If the angular measurements of a traverse are more precise than its linear measurements, balancing of the traverse, is done by
Bowditch's rule
Transit rule
Empirical rule
all of the above.
Explanation:
No answer description is available. Let's discuss.

4.
The branch of surveying in which both horizontal and vertical positions of a point, are determined by making instrumental observations, is known
tacheometry
tachemetry
telemetry
all the above.
