Question 2228 Deck Safety

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 raised, and the main deck is on the outer part of the curve, causing it to be in tension. The other options are incorrect because: A) Racking stress is a type of shear stress, not the primary stress experienced by the main deck in a hogging condition. B) Compression stress would be experienced by the bottom of the vessel, not the main deck. D) Shear stress is not the primary stress experienced by the main deck in a hogging condition.
