Aux 2 Unit 16 Q4

1 / 6

What does the term "dynamic stress" mean when referring to a vessel’s hull?

C) Stress that is evenly distributed and constant, regardless of movement

D) Stress applied only during the construction of the hull

B) Stress that results from constantly changing external forces such as waves, wind, and vessel motion

A) Stress that acts on the hull only when it is in drydock

2 / 6

Which of the following combinations correctly identifies both a dynamic and static stress on a vessel?

C) Dynamic: Hydrostatic pressure; Static: Vessel vibrations from the engine

B) Dynamic: Wind pressure on the mast; Static: Hydrostatic pressure on the hull

A) Dynamic: Weight of a cargo container; Static: Waves hitting the hull

D) Dynamic: The vessel’s total weight; Static: Passenger movement

3 / 6

Which of the following is an example of dynamic stress?

D) The internal weight of fuel tanks

B) Pressure from waves impacting the side of the ship during rough seas

A) The weight of the cargo distributed evenly across the hull

C) The hydrostatic pressure when the vessel is anchored

4 / 6

Which situation would likely increase static stress on a vessel's hull?

B) Loading heavy cargo evenly throughout the ship

A) Large waves during a storm

C) Passing over a wave crest

D) Sudden changes in wind direction

5 / 6

What is meant by "static stress" in the context of a vessel's hull?

D) Temporary stress due to loading operations

A) Stress from the propulsion system

C) Stress that fluctuates with wave height

B) A constant, unchanging load on the hull, such as the weight of the cargo and the structure of the ship itself

6 / 6

Which of the following is NOT an example of static stress?

D) The constant pressure from water acting on the submerged hull

C) The fluctuating load from passengers moving on board

B) The pressure exerted by the ship’s structure while docked

A) The stress from the weight of cargo on the deck
