Question 1881 Deck Safety

70% to pass

Vertical structural members attached to the floors that add strength to the floors are called _______________.

A stiffeners
B boss plates
C buckler plates
D breast hooks
AI Explanation

The correct answer is A) stiffeners. Stiffeners are vertical structural members that are attached to the floors of a vessel to add strength and rigidity to the floors. They help prevent the floors from bending or flexing under the weight of the vessel's structure and cargo. This is an important structural element in ship design and construction, as required by the U.S. Coast Guard regulations for commercial vessels. The other answer choices are incorrect. Boss plates and buckler plates are not specifically related to strengthening floors, and breast hooks are structural members used to connect the sides of a vessel to the deck, rather than adding strength to the floors.
