Q.1
On the sea shore structures, the water wave impact causes
  • direct compressive force due to its horizontal component
  • shear force due to deflected vertical force
  • compressive force due to collapse of the wave
  • suction force due to water returning after striking
  • all of the above.
Q.2
A dock:
  • is a marine structure for berthing of vessels for loading and unloading cargo and passengers
  • is an artificial basin for vessels where the variation of water in the shore does not affect the level of water
  • is provided with a dock gate
  • is provided with an arrangement to pump out water when required
  • all the above.
Q.3
In tropical regions,
  • the surface gets heated more effectively than the arctic areas
  • after heating, the air becomes lighter and is displaced by cool air from the polar regions
  • the rising tropical air flows towards the polar region in the upper strata
  • all of the above.
Q.4
For large vessels, the buoys are strengthened by connecting it to a number of anchors having
  • one legged mooring
  • two legged mooring
  • three legged mooring
  • four legged mooring
  • all the types as above.
Q.5
Location of soundings by two angles from the shore requires establishing
  • one range line parallel to shore
  • one range line perpendicular to shore
  • two range lines mutually perpendicular
  • no range line.
Q.6
The floating mooring does not require
  • cables
  • anchors
  • bollard
  • buoy.
Q.7
Location of soundings by range and one angle is done by the surveyor
  • on the shore
  • on the boat
  • on the shore or on the boat
  • none of the above.
Q.8
The variation of atmospheric potential is caused due to :
  • difference in temperature over the surface of the earth
  • change in the density of air
  • both (a) and (b)
  • neither (a) nor (b).
