Surveying Set 17

Q1 | The reduced level of a point on the ground is called

Q2 | If a chain is used at a temperature

Q3 | The curve of varying radius is known as

Q4 | Two theodolite method of setting out a curve involves

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

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

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

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

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

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.

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

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

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

Q14 | The angle of field of the telescope

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

Q16 | The plane table surveying is

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

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

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.

Q20 | A surface which is normal to the direction of gravity at all points, as indicated by a plumb line, is known as

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

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

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

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

Q25 | Which of the following statement is wrong?
