🔍 Key Concepts

• Distinguish between longitudinals (fore‑and‑aft members) and transverse members (athwartships) in ship construction • Understand what floors are in the context of the ship’s bottom structure and framing • Know how a double bottom is built: bottom shell, tank top, frames, and floors

💭 Think About

• Look at each option and decide: is this describing something that runs fore‑and‑aft or athwartships? How are floors normally oriented? • Which description clearly connects the structural members at the very bottom of the ship across the keel, tying the two sides together? • In a double‑bottom ship, what connects the bottom shell to the tank top: longitudinal members or transverse ones?

✅ Before You Answer

• Verify whether floors are primarily transverse or longitudinal members in ship construction terminology • Check which option mentions their role near the bottom of the ship and their connection to shell plating or tank top • Eliminate any option that is clearly describing deck beams or longitudinals rather than bottom transverse framing
