Q3.The plan of a survey plotted to a scale of 10 m to 1 cm ie reduced in such a way
that a line originally 10 cm long now measures 9 cm. The area os the reduced plan
is measured as 81 cm2. The actual area (m2) of the survey is
Answer : Option AExplaination / Solution: No Explaination.
Q5.The focal length of the object glass of a tacheometer is 200 mm, the distance
between the vertical axis of the tacheometer and the optical centre of the object
glass is 100 mm and the spacing between the upper and lower line of the diagram
axis is 4 mm. With the line of collimation perfectly horizontal, the staff intercepts
are 1 m (top), 2m (middle), and 3 m (bottom). The horizontal distance (m)
between the staff and the instrument station is
Answer : Option AExplaination / Solution: No Explaination.
Q6.A light house of 120 m height is just visible above the horizon from a ship. The
correct distance (m) between the ship and the light house considering combined
correction for curvature and refraction, is
Answer : Option DExplaination / Solution: No Explaination.
Q7.A horizontal curvature curve with a centre line radius of 200 m is provided on
a 2-lane, 2-way SH section. The width of the 2-lane road is 7.0 m. Design speed
for this section is 80 km per hour. The brake reaction time is 2.4 s, and the
coefficients of friction in longitudinal and lateral directions are 0.355 and 0.15,
respectively.
The safe stopping sight distance on the section is
Answer : Option CExplaination / Solution: No Explaination.
Q9.The ordinates of a 2-h unit hydrograph at 1 hour intervals starting from time t = 0, are
0, 3, 8, 6, 3, 2 and 0 m3/s. Use trapezoidal rule for numerical integration, if required.
What is the catchment area represented by the unit hydrograph?
Answer : Option CExplaination / Solution: No Explaination.
Q10.A taper hole is inspected using a CMM, with a probe of 2mm diameter. At a
height, Z=10mm from the bottom, 5 points are touched and a diameter of circle
(not compensated for probe size) is obtained as 20mm. similarly, a 40mm
diameter is obtained at a height Z=40mm. the smaller diameter (in mm) of hole
at Z=0 is
