🔍 Key Concepts
• A stringer plate is a fore-and-aft (longitudinal) strength member, usually a horizontal shelf of plating inside the shell, connected to frames/longitudinals.
• Distinguish between outer shell plating and internal structural members like floors, longitudinals, and stringers.
• On exam hull-structure diagrams, the stringer plate is often shown as a wide horizontal plate along the side, not at the very bottom or deck edge.
💭 Think About
• Look at each labeled letter and ask: is this part mainly vertical shell plating, or is it a horizontal internal plate running fore-and-aft?
• Which letter points to a broad, shelf-like plate along the side that ties the transverse frames together, rather than to a narrow stiffener or bar?
• Eliminate labels that clearly indicate bottom plating, deck plating, or web/frame members, leaving the one that best matches a longitudinal side shelf (stringer) plate.
✅ Before You Answer
• Verify that the piece you choose is horizontal and longitudinal, not vertical.
• Confirm it lies inside the side shell, not on the outside surface or at the very bottom plating.
• Make sure it appears to tie into frames or longitudinals as a shelf or girder, not just a thin stiffener bar.
