TACHEOMETRY MCQs 12 min Score: 0 Attempted: 0/12 Subscribe 1. A branch of surveying in which distances are measured indirectly by making observations through optical instruments is known as: (A) Contouring (B) Levelling (C) Tacheometry (D) All of these 2. The stadia diaphragm is provided for measuring: (A) Elevation (B) Bearing (C) Horizontal distance (D) Vertical distance 3. The stadia constant is denoted by: (A) (f + d) (B) f/i (C) i/f (D) (f – d) 4. The additive constant is denoted by: (A) f/i (B) (f – d) (C) i/f (D) (f + d) 5. The Subtense bar is used to measure: (A) Horizontal distance (B) Bearing (C) Elevation (D) Vertical distance 6. If the distance between the tacheometer and staff increases, then staff intercept by stadia hair will: (A) Increase (B) Decrease (C) Remain constant (D) All of these 7. Generally, value of multiplying constant is taken as: (A) Zero (B) 100 (C) 1 (D) 30 8. Subtense bar is used to find horizontal distance between two points up to such distance: (A) 200 meters (B) 100 meters (C) 150 meters (D) 50 meters 9. Stadia constant is also known as: (A) All of these (B) Constant factor (C) Multiplying constant (D) Additive constant 10. Method of tacheometry adopted when instrument has no stadia hair: (A) All of these (B) Fixed hair method (C) Moveable hair method (D) Tangential method 11. The difference of upper and lower staff readings taken by a tacheometer is called: (A) Vertical distance (B) Staff intercept (C) Inclined distance (D) Horizontal distance 12. Horizontal distance between two points can be measured with this instrument: (A) Level (B) Tacheometer (C) Compass (D) Theodolite
