UPPSC AE (CE) Quiz 30

A scale has a representative fraction of  . What will be the length measured on the ground if the length of plan is 5 cm.

What will be the length of one division of Vernier scale when length of main division of main scale is 0.2 mm and least count of Vernier is 0.12 mm

A line measuring 16 cm on plan is actually 245 m long on ground. What is the scale adopted for surveying?

Consider the following statements:

Statement 1: Shrinkage factor of a map is always less than 1.

Statement 2: Shrinkage factor is defined as the ratio of shrunk length to original length.

A plan of an area shrunk such that the line that originally measures 20 cm is now 19.8 cm only. If the original scale was 1cm = 200 m. Consider the following statements:

i. Shrunk scale will be 202.02 m = 1 cm

ii. Correct length corresponding to measured length of 10 m is 10.5 m.

Which of the following statements are correct?

Which of the following instrument is used to measure ground slope?

Statement 1: An equilateral triangle is the most appropriate well-conditioned triangle

Statement 2: A triangle is said to be well conditioned if all intersections are clear for plotting purpose.

Consider the following statements

(i) Base Line is the largest main survey line and passes through the centre of the area.

(ii) Check line is provided to check accuracy of field work.

(iii) Offset is measured in the direction of main survey line.

Which of the following statements are correct?

Match list 1 with list 2 and select the correct answer using the codes given below the lists:

List 1

P) Ranging Rod

Q) Cross Staff

R) Chains

S) Arrows

List 2

1) To measure distance between two points

2) To draw offsets perpendicular to main line

3) To mark the points measured on the chain line

4) To establish intermediate points on the survey line

A chain was designated to be 30 m long was found to be 0.2 m too long. If the measured length of chain is 354.89 m, what will be the true length
