Surveying Set 20 MCQs

Q1 | The plotting of small areas which can be commanded from a single station, is usually done on the plane table by the method of

radiation

intersection

traversing

resection

Q2 | In the surveying telescopes, cross hairs are fitted in

centre of the telescope

optical centre of the eye piece

front of the eye piece

front of the objective

Q3 | A line normal to the plumb line at all points is known as

horizontal line

vertical line

level line

line of collimation

Q4 | A back sight indicates the

shifting

setting up

height

Q5 | in measuring horizontal angles, the theodolite should be turned

clockwise from the forward station to the back station

clockwise from the back station to the forward station

anticlockwise from the forward station to the back station

anticlockwise from the back station to the forward station

Q6 | According to Lehman's rule of plane tabling

the distance to the point sought from each of the three rays is proportional to the distance of the three known points from the instrument station

when the instrument station is outside the great circle, the point sought is always on the same side of the ray drawn to the most distant point as the intersection of the other two rays

when looking in the direction of the reference points, the point sought is on the same side of each of the three rays

all of the above

Q7 | The brightness of the image

is directly proportional to

is inversely proportional to

varies directly as the square of

varies inversely as the square of

Q8 | An angle between the inclined line of sight and the horizontal is called

direct angle

vertical angle

horizontal angle

deflection angle

Q9 | The longest of the chain lines used in making a survey is generally regarded as a base line.

Agree

Disagree

Q10 | The line of collimation must be parallel to the horizontal axis.

Yes

No

Q11 | The horizon glass in an optical square is

wholly silvered

wholly unsilvered

half silvered and half unsilvered

Q12 | In a prismatic compass, the zero of the graduated ring is located at

north end

south end

east end

west end

Q13 | In tachcometric method of setting out a curve, no chain or tape is used.

TRUE

FALSE

Q14 | The axis of bubble tube must be perpendicular to the vertical axis.

Right

Wrong

Q15 | When the length of offset is 20 m, it is called

short

long

Q16 | When the centres of the arcs lie on the opposite sides of the common tangent at the junction of the two curves, it is known as a

simple curve

vertical curve

compound curve

reverse curve

Q17 | The contour interval

should be constant

need not be constant

Q18 | When several contours coincide, it indicates

a vertical cliff

a valley

a ridge

line ranger

box sextent

prismatic compass

all of these

Q20 | The positive error makes the measured distance

less than

more than

Q21 | The object of introducing a transition curve at each end of the circular curve is

to obtain a gradual increase of curvature from zero at the tangent point to the specified quantity at the junction of the transition curve with the circular curve

to provide a satisfactory means of obtaining a gradual increase of super-elevation from zero on the tangent point to the specified amount on the main circular curve

to accomplish gradually the transition from the tangent to the circular curve and from the circular curve to the tangent

all of the above
