iv 1:1600 R.F scale can written in words...........
v In prismetic compass readings mark on North is …........(o°,180°,90°)

Q-2
Describe plain scale and Draw a plain scale of RF 1:500 to represents 59 m on the scale.

OR

Write types of chain. Explain metric chain with sketch


A 20 m chain was found to be 8 cm too long after chaining a distance of 4000 m. It was tested at the end of day's work and found to be 10cm long after chaining a total distance of 7800 m. If the chain was correct before the commencement of the work, find the true distance.

Q-3

Q-4


The following consecutive readings was taken with a level and 5 m leveling staff on continuously sloping ground at a common interval of 20 meter. 0.385, 1.030, 1.925, 2.825, 3.730, 4.685, 0.625, 2.005, 3.110, 4.485. The reduced level of the first point was 208.125 mt. Calculate the reduced levels of the points by Line of collimation method. Also find the gradient of the line joining the first and last point.
