6.

A square rod of side 15 mm X 15 mm is pulled by an axial load of

60 KN.
The road extends by 0.25 mm over a gauge length of 200 mm. The latera
l
contraction on each side is 0.
006 mm. Find Poisson’s ratio and Young’s
modulus of the material of the rod.

7.

Explain the stress
-
strain curve for M.S rod

8.

The following perpendicula
r offsets were taken at 10 m intervals from a
survey line to an irregular boundary line. 3.15, 4.30, 8,20, 5.60, 6.85, 7.60,
4.20, 5.60 in meters. Calculate the area enclosed between the survey line and
the irregular boundary line using
Simpson’s rule

9.

The
following staff readings were taken with a level, the instrument having
been shifted after 3
rd

and 7
th

readings. 2.340, 1.725, 0.625, 2.890, 2.200,
1.420, 0.505, 1.485, 0.980. The bench mark of the first point is 100.00 m.
Enter the readings in a page of a

level book and calculate the reduced levels
of the points by using
Height of collimation method
.

10.

Compare between the Prismatic compass and Surveyor’s compass.
