Aux 2 Unit 16 Q2

1 / 5

How can a vessel’s hull be subject to sheer stress when it is in a seaway?

A) Due to constant and uniform pressure on the hull

B) From the alternating crests and troughs of waves, causing bending and differential forces along the hull

D) From the propeller's thrust

C) From the weight of the cargo being equally distributed

2 / 5

Which of the following best describes how sheer stress might be distributed in a vessel at rest in still water?

A) Uniformly across the hull

C) Varying along the hull, particularly where there are structural changes or weight imbalances

D) Only near the waterline

B) Concentrated at the bow only

3 / 5

How might a vessel's hull experience sheer stress while floating in still water?

A) Only during wave impact

D) From engine vibrations alone

C) Due to complete external calmness

B) From internal forces such as uneven cargo distribution or structural irregularities

4 / 5

What is the best definition of sheer stress in the context of a vessel's hull?

A) A stress that acts perpendicular to the surface of the hull

C) A type of stress that compresses the hull uniformly

D) A stress that stretches the hull lengthwise

B) A stress that acts parallel to the surface, causing one layer of material to slide over another

5 / 5

What type of movement in a seaway is most likely to increase sheer stress on the vessel's hull?

A) A gentle rolling motion

C) Slow drifting in calm waters

D) A steady cruising speed on flat water

B) Pitching, where the bow and stern move up and down due to waves
