10.5

12.5

20.5

22.5

Solution:

What is the purpose of conducting the resection method in the plane table surveying?

To determine the location of the instrument

To plot the details

To survey hilly region

To survey plain region

Solution:

An observer standing on a ship's deck sees a lighthouse. The top of the lighthouse is 30 m above the height of the observer. Calculate the distance between the observer and the lighthouse.

15 km

21 km

24 km

30 km

Solution:

If the bubble tube of a level has a sensitiveness of 35” per 2 mm division, find the error in staff reading on a vertical staff at a distance of 100 m caused by the bubble bending 3/2 divisions out of centre.

0.075 m

1.00 m

0.05 m

0.025 m

Solution:

A surveyor measured the distance between two points on the plan drawn to a scale of 1 cm = 40m and the result was 468 m. later, however, he discovered that he used a scale of 1 cm = 20 m. true distance between the points will be-

234 m

468 m

117 m

936 m

Solution:

Two distances of 20 m and 100 m were accurately measured out with the help of a tachometer and the intercepts on the staff between the outer stadia wires were 0.198 m and 0.998 m respectively. The ratio of multiplying constant to additive constant is

1000

500

250

None of these

Solution:

In a tachometric surveying the levelling staff is observed with an object glass of focal length 250mm. Determine the distance between the staff and the instrument station when the distance between the vertical axis of the tachometer and the optical center of object glass is 112mm. Consider the spacing between the upper and lower line of diaphragm axis as 3.7mm and the observed staff readings are 1.1m, 2.3m and 3.12m.
