A diagonal scale is used to read

When the length of chain used in measuring distance is longer than the standard length, the error in measured distance will be

The error which is not completely eliminated in reciprocal levelling, is

330°In a direct vernier, the smallest division of a vernier is

An invar tape is generally used for accurate measurement of distance because it possesses

When the whole circle bearing of two lines AB and AC are 115° and 41° respectively, then the included angle BAC will be

A line joining the optical centre of the object glass and the centre of the eye piece, is known as

In high latitudes, the diurnal variation of the magnetic needle is greater.

The latitude and departure of a traverse line are both positive when the whole circle bearing of the line lies in the

The curve used for ideal transition curve is a

A deflection angle is

Which of the following statement is correct?

The strength of 'fix' of a plane table from three known points is poor if the instrument station is near the great circle.

The axis of telescope level must be

To find the true difference of level between two points, the level should be kept

When the angular mesurements of a traverse are more precise than the linear measurements, the balancing of a traverse is done by

The additive constant for the tacheometer is

A compound curve consists of two arcs of equal radii bending in the same direction.

The bearing of a line in the direction of the progress of survey is called back bearing

When R is the radius of the curve (in metres), D is the degree of curve (in degrees) and length of the chord is 30°m, then the relation between R and D is
