🔍 Key Concepts

• Longitudinal bending of ships (sagging vs. hogging) • Relationship between weight distribution and buoyancy distribution along the ship’s length • Which part of the hull (deck or bottom) is in tension or compression during sagging or hogging

💭 Think About

• Think about what happens if most of the cargo or weight is concentrated in one region of the ship. How does the hull bend? • In that bending condition, which part of the ship (deck or bottom) is being stretched (tension) and which is being squeezed (compression)? • Match the bending condition that puts the bottom plating in tension with the location of the weight concentration from the choices given.

✅ Before You Answer

• Be clear on the difference: sagging vs hogging and which one puts the bottom in tension. • Visualize a simple beam supported by water pressure (buoyancy) with extra load in one region – where does it tend to bend? • Verify which weight distribution (ends, aft, forward, amidships) best creates the bending type that results in bottom tension.
