On a vessel with a single propeller,transverse force has the most effect on the vessel when the engine is put ______.
A.full ahead
B.full astern
C.half ahead
D.slow astern
第1题:
Why are most break bulk vessels built with the transverse framing system rather than the longitudinal system?
A.The transverse system is more resistant to hog and sag stresses
B.The numerous longitudinal frames cause excessive broken stowage
C.The transverse system provides better support to the varying cargo densities on a break bulk vessel.
D.The deep web frames interfere with the stowage of break bulk cargo
第2题:
A vessel is equipped with a single right-handed screw.With rudder amidships and calm wind, the vessel will most likely back ______.
A.straight astern
B.to port
C.to starboard
D.in no particular direction
第3题:
Flanking rudders effect a vessel’s heading because of the ______.
A.effect of the propeller flow on the rudders
B.water flow due to the vessel’s movement through the water
C.tunnel affect of the water flow past opposing rudders
D.discharge current being channeled to impinge on the vessel’s deadwood
第4题:
When dead in the water,it is often difficult to find the neutral position and slight headway or sternway may result
When going directly from full ahead to full astern,there is complete steering control
When the vessel has headway and the propeller is in neutral,there is no effect on rudder control
When maneuvering in port,full ahead or astern power can usually be obtained without changing shaft RPM
第5题:
furnishes support to the rudder,propeller shaft,and transom frame
provides foundations for after mooring winches
provides foundations for the main propulsion engines
transfers the driving force of the propeller to the hull
第6题:
KB increases,increasing BM and therefore GM
KG increases due to the weight of the added water on deck
BM decreases from loss of water plane and greater volume
There is no effect on transverse stability
第7题:
effect of the propeller flow on the rudders
water flow due to the vessel's movement through the water
tunnel affect of the water flow past opposing rudders
discharge current being channeled to impinge on the vessel's deadwood

pitch
surge
sway
heave
第9题:
It pulls the bow toward the bank

half ahead
slow astern
第12题:
backing
going slow ahead
going full ahead
turning
第13题:
The correction to KG for longitudinal free surface effects for a vessel can be found by dividing the vessel's displacement into the ______.
A.Transverse free surface correction for the vessel
B.Sum of the vertical moments of the vessel
C.Sum of the longitudinal free surface moments of the vessel
D.Longitudinal centerline of the vessel
第14题:
Aboard a vessel, dividing the sum of the transverse moments by total weight yields the vessel’s
A.vertical moments
B.transverse position of the center of gravity
C.inclining moments
D.righting moments
第15题:
For a vessel inclined by the wind, multiplying the buoyant force by the horizontal distance between the lines of action of the buoyant and gravity forces gives the ______.
A.righting moment
B.longitudinal moment
C.transverse moment
D.vertical moment
第16题:
furnishes support to the rudder, propeller shaft, and transom frame
provides foundations for after mooring winches
provides foundation for the main propulaion engines
transfers the driving force of the propller to the hull
第17题:
discharge current
suction current
sidewise force
thrust
第18题:
back current from the rudder
greater pressure on the right or left side of the propeller,depending on rotation
lower pressure on the right or left side of the propeller,depending on rotation
torque from the velocity and angle at which the surrounding water impinges upon the propeller blades
第19题:
It forces the bow away from the bank
It forces the stern away from the bank
It forces the entire vessel away from the bank
It heels the vessel toward the bank
