Q

Where do signs of racking stresses generally appear on the vessel?

🔍 Key Concepts

• Racking stress is caused by rolling and deforming the ship’s transverse (side-to-side) structure • Think about where frames, beams, and floors meet and how the hull resists side-to-side distortion • Consider which areas are most involved in supporting the ship’s transverse strength, not longitudinal (front–back) strength

💭 Think About

• When the ship rolls, which parts of the internal structure are trying to twist out of square, like a box being pushed sideways? • Which answer choice describes the main intersection points of the transverse structural members that form the ship’s ‘box’ structure? • Which options can you eliminate because they relate more to longitudinal strength, shafting, or bottom/keel strength rather than transverse distortion?

✅ Before You Answer

• Be clear on the difference between racking stress (transverse/rolling) and longitudinal bending (hogging/sagging) • Identify where frames, beams, and floors come together and what type of stress they mainly experience • Eliminate choices that focus on propulsion machinery, keel/garboard plating, or local bow/stern shell rather than overall transverse hull distortion
