Question 1888 Deck Safety

The correct answer is D) a deck beam does not lessen the longitudinal stiffness of the vessel. A deck beam acts as a beam to support vertical deck loads (option B) and as a tie to keep the sides of the ship in place (option A). It also acts as a web to prevent plate wrinkling due to twisting action on the vessel (option C). However, the deck beam does not lessen the longitudinal stiffness of the vessel. Rather, the deck beam is an important structural component that helps maintain the overall longitudinal strength and rigidity of the ship's hull.
