341. During plane table survey, the figure indicates which of the following procedures? [BB-20]
two point problem
three point problem
compass orientation
back sight orientation
342. The value of representative fraction of a map is 1: 10000 then what is the measurement in map for actual distance 500m? [MOD-20]
5m
5cm
5mm
5in
10000 cm represents = 1cm 50000 (500x100)cm represents = 10000 cm = 5cm
343. Length of Transition Curve = 150m. Length of Circular Curve = 1200m and Radius of Curvature = 1000m. The Shift (S) is- [PBRLP-21]
1m
0.94m
0.97m
1.1m
344. The contour intervals depends on the-. [MOD-20]
nature of the ground
scale of map
purpose and extend of survey
all of these
The choice of suitable contour interval in a map depends upon four principal considerations, These are- (i) Nature of the Terrian, (ii) Scale of the Map, (iii) Accuracy, (iv) Time of Cost.
345. For a traverse containing 10 sides, what would be the correction applied for the first side, if it consists a closing error of + 1.92? [BB-20]
19.0
19.2
1.902
0.192
The correction for sides in a traverse is given as correction = e/N, where N is the number of sides and e is the closing error. On substitution, we get, correction = 1.92/10 = 0.192.
346. If staff reading of two points A and B is 5.7 ft and 6.85 ft respectively and RL for point A is 100 ft then what is the RL of point B. [MOD-20]
101.15 ft
98.85 ft
105.6 ft
102.5 ft
347. Back bearing of a line is equal of [BPSC-22]
Fore bearing ±90°
Fore bearing ±180°
Fore bearing ±270°
Fore bearing ±360°
Back bearing (BB) = Fore Bearing (FB) ±180° (+) ve signis used if FB is less @ than 180° এবং (-) ve sign is used if FB is more than 180°
348. Rise and fall method is used in-.
profile levelling
differential levelling
check levelling
none
It consists of determining the difference of elevation between consecutive points by comparing each point after the first that immediately preceding it. The difference between their staff reading indicates a rise fall according to the staff reading at the point.
349. The optical square is used to measure angles by-[MOD-20]
refraction
reflection
double refraction
double reflection
350. The constant vertical distance between two adjacent contours is called[BPSC-22)
Horizontal interval
Vertical interval
Contour interval
Contour distance
The constant vertical distance between two adjacent contour is called contour interval and horizontal distance between two contours is known contour gradient.
351. Which one is not surveying instrument? [MOD-20]
Theodolite
Plane table
Microscope
Level machine
Chains and Tapes. Taking accurate measurements is one of the most important tasks a land surveyour must complete.... Compasses and Clinometers, Transits and Theodolites, Levels, Safety Gear, Prisms and Reflectors, Magnetic Locators, Poles, Tripods and Mounts.
352. The method of surveying in which field work and plotting work are done simultaneously is called- [MOD-20]
compass surveying
levelling
plane table
chain surveying
Plane table surveying is a graphical method of survey in which the field observations and plotting are done simultaneously. It is simple and cheaper than Theodolite survey but it is mostly suitable for small scale survey.
353. There are two stations A and B. Which of the following statements is correct? [BB-20]
The fore bearing of AB is AB
The back bearing of AB is BA
The fore and back bearings of AB differ by 180°
All of the above
354. If the line AB have forward bearing 130° then what is the backward bearing? [MOD-20]
50°
220°
310°
30°
355. A closed contour line with one or more higher ones inside to represent -[BB-20]
hill
pond
river
cliff
A closed contour line with one or more higher ones inside to represent a hill. Similarly closed contour line with one or more lower ones inside it indicates a depression without an outlet.
356. RL of MSL at the Bay of Bengal near Cox Bazar is- [BPSC-22]
10m
50m
100m
MSL means sea level. Mean sea level at the Bay of Bengal considered near Cox Bazar. R.L of MSL at the Bay of Bengal near Cox bazar is 0 (Zero).
357. যখন মাপা দূরত্ব প্রকৃত দূরত্ব হতে কম হয় তখন এই ভুলকে বলা হয়-
স্পট ভুল
ঋণাত্মক ভুল
ক্ষতিপূরণীয় ভুল
যান্ত্রিক ভুল
358. Contour interval is- [BB-20]
the vertical distance between two consecutive contours
the horizontal distance between two consecutive contours
the vertical distance between two points on same contours
the horizontal distance between two points on same contour
A contour in the survey is the vertical distance or the difference in elevation between the two contour lines on a topographic тар.
359. The contour lines of different elevations-[BADC-22]
cross each other at right angles
cross each other at 45° angles
do not cross each other
cross each other at random
360. During survey of an engineering project, the laws of accidental errors follow which of the following principle? [BB-20]
normal equation
probability law
laws of weight
most probable value
Laws of accidental errors follow the probability law, Which is having a definite law for accidental error accurence. It defines the errors and helps in expressing them in the form of equations.
