Derive the relationship between the radius and the degree of curve. What are the basic criteria for the design of transition curve? What do you mean by extension of base line? How is it done? Draw the figure for arrangement of centred triangle and polygon. List the Laws of Weight. Explain the method of least square. What fundamental quantities can be measured by a total station? Distinguish between terrestrial photogrammetry and aerial photogrammetry: (2 x 10) a) Find the focal length of anallactic lens and distance at which it should be placed to get a multiplying constant of 100 from the following data: Focal length of objective lens = 24cm, stadia interval = 0.17cm, distance between the objective lens and vertical axis = 10.5cm. (5) b) A tacheometer is placed at a station A and readings on a staff held vertical upon a B.M. of RL =100.0 meter and at station B are 0.640, 2.200, 3.760 and 0.010, 2.120, 4.230 m respectively. The angle of depression of the telescope in the first case is 6° 19' and in the second case is 7° 42'. Find the horizontal distance from A to B and the RL of station B, if the instrument has constants 100 and 0.5 (5) a) Draw with neat sketch a simple curve showing the elements of it. (4) b) Two parallel railway lines are to be connected by a reverse curve. If the lines are 10m apart, and the maximum distance between tangent points measured parallel to the straight is 50m. Find (a) the radius R if R1 = R2 = R (b) the radius R2 if R1 = 50m (c) Also calculate the lengths of both the curves. (6) a) List the factors considered while selecting the site for base line. (4) b) Two triangulation stations A and B are 60 km apart and the elevation of A is 240 m and that of ground at B is 280 m. Find the minimum height of a signal required at B so that the line of sight may not pass near the ground than 2.0 m. Assume elevation of intervening ground uniformly as 210 m. (6)
