First Year Engineering (Semester 2)

TOTAL MARKS: 100
TOTAL TIME: 3 HOURS (1) Question 1 is compulsory.
(2) Attempt any four from the remaining questions.
(3) Assume data wherever required.
(4) Figures to the right indicate full marks. 1(a) Explain the fundamental principles of surveying(7 marks) 1(b) The distance between two points on the ground was measured with 30 m chain and found to be 1500 m. The same distance was measured with a 20 m chain and found to be 1450 m. If the 30 m chain was 5 cm too short, what was the error in the 20 m chain? (7 marks) 2(a) The following staff readings were taken on a uneven ground with a 4 m leveling staff. Calculate reduced levels of all the points by Height of instrument method and apply usual checks. The instrument was shifted after 3 ^rd , 6th and 9 th readings. Thefirst reading was taken on a bench mark of 100 m
1.20 , 2.65, 3.50, 2.40, 1.95, 0.90, 1.80, 3.70, 2.50, 0.85, 1.70 (7 marks) 2(b) Define:
