Q2.A box contains 4 white balls and 3 red balls. In succession, two balls are randomly selected and removed from the box. Given that the first removed ball is white, the probability that the second removed ball is red is
Answer : Option CExplaination / Solution: No Explaination.
Q3.Consider a simply supported beam with a uniformly distributed load having a neutral axis (NA) as shown. For points P (on the neutral axis) and Q (at the bottom of the beam) the state of stress is best represented by which of the following pairs?
Answer : Option AExplaination / Solution: No Explaination.
Q6.A field vane shear testing instrument (shown alongside) was inserted completely
into a deposit of soft, saturated silty clay with the vane rod vertical such that the
top of the blades were 500 mm below the ground surface. Upon application of a
rapidly increasing torque about the vane rod, the soil was found to fail when the
torque reached 4 6. Nm. Assuming mobilization of undrained shear strength on
all failure surfaces to be uniform and the resistance mobilized on the surface of
the vane rod to be neglibible, what would be the peak undrained shear strength
(rounded off to the nearest integer value of kPa) of the soil?
Answer : Option BExplaination / Solution: No Explaination.
Q8.The depth of flow in a alluvial channel is 1.5 m If critical velocity ratio is 1.1 and
Manning’s n is 0.018, the critical velocity of the channel as per Kenedy’s method
is
Answer : Option BExplaination / Solution: No Explaination.
Q10.A sand layer found at sea floor under 20m water depth is characterized with relative
density = 40%, maximum void ratio = 1.0, minimum void ratio = 0.5, and specific
gravity of soil solids = 2.67. Assume the specific gravity of sea water to be 1.03 and the
unit weight of fresh water to be 9.81kN/m3.
What would be the effective stress (rounded off to the nearest integer value of
kPa) at 30m depth into the sand layer?
