LEVELLING SURVEY - Practice Mode

1) What level is required for permanent adjustment if the bubble axis made parallel to collimation axis of the telescope?

Auto level Tilting level Dumpy level Target level

Correct Answer: Tilting level

2) What is the difference of level if dumpy level is at mid point C Staff reading on A = 1.580m Staff reading on B = 1.220m?

2.700m 1.360m 0.360m 0.630m

Correct Answer: 0.360m

3) What is the height of collimation if reduced level of point A= 100.000m. Back sight at point A = 2.750m?

12.750m 98.250m 102.750m 101.750m

Correct Answer: 102.750m

4) What is R.L of point, if the height of collimation level 103.450m and inter sight reading on point 1=2.680m?

106.130m 105.130m 100.077m 100.77m

Correct Answer: 100.77m

5) What is rise or fall, if back sight reading taken on B.M is 2.045m and inter sight on point =2.68m?

-0.735 fall -0.635 fall +0.735 Rise +0.635 Rise

Correct Answer: -0.635 fall
