Pick out the correct statement(s) from the following. Direct ranging is done when the two ends of the survey lines are inter-visible. Reciprocal ranging is done when the survey lines are not inter-visible due to long distance. Ranging by line ranger is used for fixing intermediate points on a long line. All of the above3. Which type of survey is used in fixing of property lines, the calculation of land area, or the transfer of land property from one owner to another? Cadastral survey Geological survey Hydrographic survey Topographical survey4. Wing nuts are provided on ______ Tripod Standards Bubble tubes Diaphragm5. The process of turning the telescope in vertical plane through 180o about the trunnion axis in a theodolite is known as Swinging Centring Transiting None of the above6. What is the essential condition to be fulfilled in orientation of plane table surveying when more than one instrument station is to be used. Direction on the plan is to be parallel to the direction on the ground Direction on the plan is to be perpendicular to the direction on the ground Direction on the plan is to be clockwise to the direction on the ground Direction on the plan is to be anti-clockwise to the direction on the ground7. What does the Chainage in chain survey refers to? The given distance between two points The parallel distance of the object from the chain line Any distance measured by chain in field The distance of the object measured along the chain line from starting point of the chain8. If the length of a line measured with a 20m chain and incorrect length L’ of a chain is 20.1m and measured length l’ is 250m, then what is the ‘true length’ of the line?250meters 251.25meters 250.25meters 251meters9. If the mean temperature Tm in the field during measurement is 35kg and temperature during standardization of the tape To is 15kg, the measured length is 1000 and coefficient of thermal expansion is 12 x 10-6. What is the temperature correction of the tape? 0.200m 0.240m 0.280m 0.160m10. Which of the following conditions are to be fulfilled by survey lines for a good system of lines in a survey station?(i) Survey stations must be mutually visible.(ii) The lines must run through level ground as possible.(iii) The main lines should from well-conditioned triangles.(iv) The framework in survey lines must have one or two survey lines. only (iii) is required (i), (iv), (ii) are required All of the above None of the above11.
