This set of Surveying Multiple Choice Questions & Answers (MCQs) focuses on Surveying Set 12

Q1 | When the anallatic lens is provided in the telescope of a tacheometer, the additive constant is zero.
• Agree
• Disagree
Q2 | In order to determine the natural features such as valleys, rivers, lakes etc., the surveying preferred is
• city surveying
• location surveying
• topographical surveying
Q3 | An angle made by a survey line with the prolongation of the proceeding line, is known as
• direct angle
• vertical angle
• horizontal angle
• deflection angle
Q4 | The bearing observed with a prismatic compass is
• whole circle bearing
Q5 | Due to the magnetic influence of the earth, the magnetic needle of the prismatic compass will be inclined downward towards the pole. This inclination of the needle with the horizontal is known as
• true bearing
• dip
• local attraction
• magnetic declination
Q6 | The real image of an object formed by the objective must lie at the centre of telescope.
• Agree
• Disagree
Q7 | The direction of a true meridian at a station is invariable.
• Right
• Wrong
Q8 | In a whole circle bearing system N 25? 15' W corresponds to
• 115? 15'
• 154? 45'
• 205? 15'
• 334? 45'
Q9 | An open cross-staff is commonly used for setting out
• short offsets
• long offsets
• oblique offsets
• none of these
Q10 | The adjustable cross-staff is used for setting out an offset
• at an angle of 45?
• at an angle of 60?
• at a right angle
• at any angle
Q11 | To the sum of the first and last ordinates, add twice the sum of the intermediate ordinates. The total sum thus obtained is multiplied by the common distance between the ordinates. One-half of this product gives the required area. This rule of finding the area is called
• mid-ordinate rule

• nearer
• farther
Q15 | The angle by which the forward tangent deflects from the back tangent of a curve is called
• deflection angle
• central angle
• angle of intersection
• none of these
Q16 | If the fore bearing of a line is N 26? 35' W, its back bearing will be
• S 26? 35' E
• S 26? 35' W
• N 26? 35' E
• N 53? 25' W
Q17 | A staff reading taken on a bench mark or a point of known elevation is called

• a single curve of a circle connecting two straights
• two arcs of different radii bending in the same direction
• two arcs of equal radii bending in the same direction
• two arcs of equal or different radii bending in the opposite directions
