Which method of traversing is also known as free or loose needle method?
Chain traversing
Plane table traversing
Transit tape traversing
Chain and compass traversing
The most accurate method of transit tape traversing is:
Fast needle method
Back bearing method
Direct observation of angles
Free needle method
Deflection angles are especially suitable for surveys of:
Closed polygons
Small plots
Roads and railways
Building layouts
A traverse that does not return to its starting point is called:
Closed traverse
Dependent traverse
Open traverse
Control traverse
Latitude of a traverse line of length l and bearing θ is given by:
l sin θ
l tan θ
l cos θ
l sec θ
Bowditch’s rule is used for balancing traverse when:
Linear measurements are more precise
Angular measurements are more precise
Both linear and angular measurements are equally precise
Traverse is open
Chain traversing is considered unsuitable for accurate work.
True
False
Transit tape traversing by fast needle method measures the bearing of the (a) line directly.
Included angles are preferably measured (a) from the back station.
—-——is the angle which a traverse line makes with the prolongation of the preceding line.
(a)
In an open traverse, arithmetic checks are (a) available.
Latitude is the projection of a traverse line on the (a) direction.
Departure is measured (a) to the assumed meridian.
The formula for closing error e is √( (ΣL)² + (ΣD)² ), where ΣL and ΣD are sums of __________ and __________.
(a)
Balancing of traverse is mainly applicable to (a) traverse.
