Question 2230Deck Safety70% to pass
When a vessel is stationary and in a hogging condition, the main deck is under _______________.
AI Explanation
The correct answer is C) tension stress.
When a vessel is stationary and in a hogging condition, the main deck is under tension stress. This is because in a hogging condition, the center of the vessel is bent upwards, causing the main deck to be stretched and placed under tension. The opposite is true for a sagging condition, where the main deck would be under compression stress.
The other answer choices are incorrect because: A) compression stress applies to the bottom of the hull in a hogging condition, not the main deck; B) racking stress is caused by lateral forces, not the vertical bending of the hull; and D) shear stress occurs between adjacent structural members, not directly on the main deck.
