Question 2231Deck Safety70% to pass
If a vessel is sagging, what kind of stress is placed on the sheer strake?
AI Explanation
The correct answer is C) Compression.
When a vessel is sagging, the sheer strake (the uppermost strake or plating on the side of a ship's hull) experiences compression stress. This is because the sagging motion causes the middle of the vessel to dip downwards, while the ends are raised upwards. This puts the sheer strake under compressive forces, as it is being squeezed or pushed inwards towards the center of the vessel.
The other answer choices are incorrect because thrust is a force acting on the propulsion system, tension would be experienced in a hogging condition, and racking refers to a different type of structural deformation not associated with sagging.
