🔍 Key Concepts

• Longitudinal strength of a ship's hull girder • How bending moments and shear forces vary along the length of a beam (the ship) • Typical locations of maximum shear vs maximum bending moment on a simply supported beam

💭 Think About

• Imagine the ship as a long horizontal beam in a seaway: where would the upward buoyant force and downward weight cause the largest change in load along the length? • Think about where on a loaded ship the distribution of weight (cargo, machinery) and buoyancy (underwater volume) are most different from each other. • In basic beam diagrams from strength of materials, where do you usually see the peak shear force in relation to the bow, stern, midships, and quarter-lengths?

✅ Before You Answer

• Distinguish clearly between where bending moment is maximum and where shear force is maximum along a beam. • Visualize or sketch a simple shear force diagram for a uniformly loaded beam with supports near the ends and see where the peak shear occurs. • Confirm that you are thinking about shear stresses in the hull girder (longitudinal strength), not local stresses at the bow or stern fittings.
