Question 1889 Deck Safety

The correct answer is A) racking stresses. Deck beam brackets on a transversely framed vessel are designed to resist racking stresses, which are shear stresses caused by the deformation of the vessel's hull. Racking occurs when the sides of the vessel move relative to each other, causing the deck beams to experience shear loads. The deck beam brackets help transfer these racking stresses into the vessel's framing, preventing excessive deformation and ensuring the structural integrity of the hull. The other answer choices are incorrect because: B) Sagging stresses are longitudinal bending stresses, which are primarily resisted by the vessel's keel and longitudinal framing. C) Shearing stresses are not directly resisted by the deck beam brackets, but rather by the overall structural framing of the vessel. D) Hogging stresses are the opposite of sagging stresses, and are also primarily resisted by the vessel's longitudinal framing.
