Aux 2 Unit 16 Quiz 3

Correct Answer:
C) The bow

Explanation:
The bow experiences the most force during pounding as it is the part of the vessel that hits the water first after being lifted by a wave.

Correct Answer:
B) Installing longitudinal girders and panting stringers at the bow

Explanation:
Panting stringers and additional girders are installed at the bow to reinforce the hull and resist the expansion and contraction caused by panting.

Correct Answer:
B) Reinforced deck beams and bulkheads near the bow

Explanation:
Reinforced deck beams and bulkheads near the bow help distribute the impact forces from pounding, reducing localized stress and preventing structural damage.

Correct Answer:
B) The impact of the vessel's bow slamming into the water when it rises and falls forcefully

Explanation:
Pounding occurs when the bow of the vessel lifts out of the water due to wave action and then slams back down, impacting the water with significant force. This can cause stress on the hull.

Correct Answer:
B) By reinforcing the forward bottom plating with thicker steel or additional frames

Explanation:
To resist the stresses from pounding, the forward bottom plating is often made thicker, and additional framing is added to strengthen the area and absorb impact forces.

Correct Answer:
B) The rapid movement of the bow through waves causes both slamming impacts (pounding) and pressure fluctuations (panting)

Explanation:
In heavy seas, the bow's motion through large waves leads to both the impact of pounding and the alternating pressure changes that cause panting.

Correct Answer:
B) The expansion and contraction of the hull plating due to pressure changes as the vessel moves through waves

Explanation:
Panting occurs when the hull plating near the bow or stern expands and contracts due to the varying pressure exerted by waves, especially in heavy seas.
