The operation in which the plumb line of a theodolite passes through the ground station mark is called

• Setting up

• Leveling

• Centering

• Transiting

The departure of a line is obtained by

• $L\cos\theta$

• $L\ \cos^2\ \theta$

• $L\ \tan\ \theta$

• $L\ \sin\theta$

The linear misclosure is generally expressed as a fraction of

• perimeter of traverse / closing error

• perimeter of traverse / bearing

• distance / perimeter of traverse

• angle / perimeter of traverse

For a closed traverse, which check is more important and essential? Choose two answers.

• $\Sigma\ Latitude\ =\ 0$

• $\Sigma\ Departure\ =\ 0$

•  $\Sigma\ coordinates\ =\ 0$  

• F.B - B.B = 180

If n is the number of sides of a traverse, while traversing clockwise the sum included angles should be

• $\left(2n\ +4\right)\ 90\degree$

• $360\degree$

• $\left(2n\ -\ 4\right)\ 90\degree$

• $\left(n\ -\ 4\right)90\degree$

In traversing, the traverse can be

• Closed

• Open

• Closed with central station

• Closed or open

Latitude of a line is defined as

• Orthographic projection of a survey line on the E-W line

• Orthographic projection of a survey line on the reference meridian

• None of the above

Bearing of line A to B is  $127\degree$  and apart by 304.50 meter and . The Latitude of line AB is

• 71.934

• -0.602

• 243.185

• -183.253

A traverse survey work can be classify as 2^nd class order when its linear misclosure is 1:6780

• TRUE

• FALSE

 $\tan^{-1}\ \frac{error\ latitude}{error\ departure}$  is the formula to determine angular misclosure

• TRUE

• FALSE
