š Key Concepts
ā¢ A stringer plate is a fore-and-aft (longitudinal) strength member, usually a horizontal shelf of plating inside the shell, connected to frames/longitudinals.
ā¢ Distinguish between outer shell plating and internal structural members like floors, longitudinals, and stringers.
ā¢ 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.
š Think About
ā¢ 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?
ā¢ 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?
ā¢ 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
ā¢ Verify that the piece you choose is horizontal and longitudinal, not vertical.
ā¢ Confirm it lies inside the side shell, not on the outside surface or at the very bottom plating.
ā¢ Make sure it appears to tie into frames or longitudinals as a shelf or girder, not just a thin stiffener bar.
