- angular measurements only
- both linear and angular measurements
- none of these

Q5 | A fixed point of reference of known elevation is called

- change point
- station point
- bench mark
- datum

Q6 | The correction to the measured length will be negative when the chain is held on the ground sloping upwards.

- Yes
- No

Q7 | When the object lies on the left hand side of the chain line, then while taking offset with an optical square, it is held in

- left hand upside down
- right hand upside down
- left hand upright
- right hand upright

Q8 | A method of differential levelling is used in order to find the difference in elevation between two points when

- they are too far apart
- there are obstacles between them
- the difference in elevation between them is too great
- all of the above

Q9 | A metallic tape is made of an alloy of nickel and steel.

- TRUE
- FALSE

Q10 | When a staff is sighted through the telescope, a certain length of staff is intercepted by the stadia lines. The staff intercept varies with the distance at which the staff is held.

- Yes
- No

Q11 | With a simple vernier, readings can be taken in one direction only.

- Yes
- No

Q12 | In railway and highway works, the method of measuring the

- direct angles
- deflection angles

Q13 | The contour interval of any survey is inversely proportional to the scale of the map.

- Agree
- Disagree

Q14 | The angle of field of the telescope

- is independent of the size of the object galss
- increases as the size of the eye piece increases
- decreases as the distance between eye piece and object increases
- all of the above

Q15 | For accurate work, the lengths of back sight and fore sight are kept unequal.

- Agree
- Disagree

Q16 | The plane table surveying is

- most suitable for preparing small-scale maps
- particularly advantageous in magnetic areas
- less costly than a theodolite survey
- all of the above

Q17 | The line in which the plane passing through the given point and the north and south poles intersects the surface of the earth, is called

- arbitrary meridian
- magnetic meridian
- true meridian
- none of these

Q18 | A scale used for measuring fractional parts of the smallest division of the main scale is known as vernier scale.

- Correct
- Incorrect

Q19 | To the sum of the first and last ordinates, add twice the sum of the remaining odd ordinates and four times the sum of all the even ordinates. The total sum thus obtained is multiplied by one-third of the common distance between the ordinates and the result gives the required area. This rule of finding the area is called.

- mid-ordinate rule

- vertical surface

Q21 | The error in measured length due to sag of chain or tape is known as

- positive error
- negative error
- compensating error
- instrumental error

Q22 | When the latitudes and departures are so adjusted that the algebraic sum of the latitudes and departures are equal to zero, the operation is called

- balancing the latitude
- balancing the departure
- balancing the traverse
- none of these

Q23 | In plane tabling, the instrument used to measure horizontal and vertical distances directly, is known as

- tacheometer
- clinometer

Q24 | When the whole circle bearing of a traverse line is between 90? and 180?, then

- the latitude is positive and departure is negative
- the departure is positive and latitude is negative
- both the latitude and departure are positive
- both the latitude and departure are negative

- A series of closed contour lines on a plane indicates a hill if the higher values are outside.
- The uniformly spaced contour lines indicates a plane surface.
- all of the above
