2(a) The following notes refers to the reciprocal leveling:
 Instrument Station Staff  readings  on Remarks A B A 1.030 1.63 Distance  between A and B = 800m  R L  of  A is 440. B 0.950 1.54

8 M
2(b) Write a detailed note on obstacles in chain surveying.
7 M
2(c) A line was measured with steel tape which was exactly 30m at a pull of 5kg and measured length 229.62m. The pull applied during measurement was 10kg and the tape was uniformly supported. Find the true length of line if the cross- sectional area of tape was 0.02cm 2and modulus of elasticity of tape material = 2.1×105 kg/cm2.
