Aux 2 Unit 16 Quiz 8

Correct Answer:
A) When the bow and stern are unsupported and the midship section is supported by a wave, causing upward bending

Explanation:
Hogging occurs when the vessel's midsection is lifted by a wave, while the bow and stern are not supported, creating upward bending stress along the length of the ship.

Correct Answer:
C) The forceful impact of the bow slamming against the water when the vessel moves over waves

Explanation:
Pounding is the slamming effect experienced by the bow when it rises out of the water and then forcefully crashes back into it, creating high impact forces that stress the hull structure.

Correct Answer:
A) The downward bending of the vessel when the midsection is not supported by water and the bow and stern are supported by waves

Explanation:
Sagging is the opposite of hogging, where the bow and stern are supported by wave crests, but the midsection is in a trough, leading to downward bending.

Correct Answer:
B) The twisting or lateral deformation of the vessel due to side-to-side forces, such as rolling in heavy seas

Explanation:
Racking occurs when lateral forces, like those from rolling in rough seas, cause the ship's structure to twist or deform side-to-side.

Correct Answer:
B) The repetitive in-and-out movement of the hull plating due to varying pressure when the vessel pitches in waves

Explanation:
Panting is caused by the varying pressure on the hull as the vessel moves through waves, leading to expansion and contraction of the plating, especially near the bow.
