OR
(b) Enlist various instruments used in chaining and describe with sketch 07 any two of them.
Q.3
(a) Explain with sketch the open cross staff and its use for setting out the 05 right angle to a chain line.
(b) Describe the procedure of temporary adjustment of a prismatic 05 compass. Also, differentiate between prismatic compass and surveyors compass.
(c) A survey line AB intersects a pond as an obstacle. A and B are on the 04 either side. To continue the line passing this obstacle, station M and N
are taken such that M, B and N are on the same straight line. Distances AM, MB, BN and AN are measured to be 150m, 100m, 120m and 200m respectively. Find the length of line AB.
OR
Q.3

Where do you suspect the local attraction? Find the included angles and corrected bearings of the lines. |
Q.4
(b) Describe with a sketch, the planimeter and explain how will you 05 determine the area of irregular figure using it.
(c) The following readings were taken with a dumpy level and 4m 05 leveling staff. The instrument was shifted after 3rd and 6th readings.
The readings are: 2.665, 3.225, 2.905, 1.850, 0.980, 2.620, 1.585,
0.960, 0.425m. Enter the above readings in a page of level book and calculate the RL of points, if the first reading was taken with a staff held on a benchmark of 240m. Use rise and fall method. Apply arithmetic check also.
OR
Q. 4
(b) Draw detailed sketch showing various components of typical highway 05 cross section in embankment. List various types of materials used in highway construction and explain any one of them in detail.
