Question 181Safety & Environmental - Assistant Engineer
70% to passIt is generally not advisable to drive a wedge into a crack occurring in the hull because wedges _______________.
Awill pull through the plating
Bwill splinter
Ctend to open the crack
Dwill work loose
AI Explanation
The correct answer is C) tend to open the crack. Driving a wedge into a crack in the hull is generally not advisable because the wedge will tend to open the crack further, potentially causing more damage to the hull. Wedges are not an effective solution for repairing cracks in a vessel's hull, as they can actually exacerbate the problem by prying the crack open rather than closing it. The other options are incorrect because: A) the wedge may pull through the plating rather than hold the crack closed, B) the wedge could splinter and create additional hazards, and D) the wedge is likely to work loose over time, failing to provide a lasting repair.
