2.A steel tape 20 m long standaridized at 55⁰F with a pull of 10 kg was used for measuring a base line .Find the correction per tape length .If the temperature at the time of measurement was 80⁰ F and the pull exected was 16 kg weight of tape 0.8 kg and E=2.109×10⁶ kg/cm² co-efficientt of expansion of tape per 1⁰F =6.2×10⁶

3.  P and Q are two points 5,7 m apart on the sume  bank of river.The bearing of a tree on the other bank observed from P and Q are N33⁰ 44’ E and N 43⁰ 20’W respectively .Find the width of river if the bearing of PQ is 78⁰F.

     4. The following bearings  were observed while traversing with a compus

                                                         

Line	FB	BB
AB	45045’	226010’
BC	96055’	277005’
CD	29045’	209010’
DE	324048’	144048’

Mention which stations were affected by local attraction and determine the corrected bearings.

5. The bearings of the sides of a closed traverse  ABCDEA are as follows

side	FB	BB
AB	1070 45’	2870 15’
BC	220 00’	2020 00’
CD	2810 30’	1010 30’
DE	1890 15’	90 15’
EA	1240 45’	3040 45’

Compute the interior angle of the traverse.
