Q3. A test plate 30m × 30m cm resting on a sand deposit settles by 10 mm under
a certain intensity. A footing 150cm × 200cm resting on the same sand deposit
and loaded to the same load intensity settles by
Answer : Option B

Q4. The expression ((x + Y) - |x - y|)/2 is equal to
Answer : Option B
Explaination / Solution:
Q5. Consider a reinforcing bar embedded in concrete. In a marine environment this bar undergoes uniform corrosion, which leads to the deposition of corrosion products on its surface and an increase in the apparent volume of the bar. This subjects the surrounding concrete to expansive pressure. As a result, corrosion induced cracks appear at the surface of concrete. Which of the following statements is TRUE?
Answer : Option C
Explaination / Solution:
No Explaination.
Q6. A rectangular open channel of width 4.5 m is carrying a discharge of 100 m3 sec.
The critical depth of the channel is

Q9. The cross-section of a thermo-mechanically treated (TMT) reinforcing bar has
Answer : Option C
Explaination / Solution:
No Explaination.
Q10. Water(γw = 9.879 kN/m3) flows with a flow rate of 0.3 m3 sec through a pipe AB
of 10 m length and of uniform cross-section. The end B is above end A and the
pipe makes an angle of 30o to the horizontal. For a pressure of 12 N/m2 at the
end B, the corresponding pressure at the end A is
