🔍 Key Concepts

• Transverse framing system: how deck beams, frames, and brackets connect • How brackets work to keep right angles between deck and side shell • Difference between longitudinal bending (hogging/sagging) and distortion of the ship’s cross-section

💭 Think About

• Think about what happens to the ship’s shape in heavy seas: which kind of stress mainly bends the ship lengthwise, and which tries to twist or distort the rectangular shape of deck and sides? • What job does a deck beam bracket do at the corner where the deck meets the side frame: is it mainly carrying vertical bending, sliding forces, or preventing the frame and beam from going out of square? • Which of the listed stresses would try to turn a rectangle (deck + side shell) into a parallelogram, and which would simply bend the hull up or down along its length?

✅ Before You Answer

• Identify which options (hogging, sagging) are longitudinal hull bending effects, not local bracket duties • Decide which choice relates to distortion of the ship’s transverse shape (side + deck going out of square) • Confirm that brackets at beam-to-frame connections are primarily there to resist deformation of the transverse framework, not overall hull bending
