🔍 Key Concepts

• Deck structural members on ships and MODUs (e.g., longitudinals, beams, girders, frames, stanchions) • The difference between primary supporting members and secondary/local supports in a deck structure • Typical phrase used: "deck plating is supported by deck ______ and deck ______" in standard ship construction texts

💭 Think About

• Think about which members run transversely under the deck plating to support it between longitudinals. • Consider which listed members are mainly vertical supports versus horizontal deck supports. • Ask yourself: In basic ship construction, when you describe support for deck plating, what pair of terms is most commonly used together?

✅ Before You Answer

• Verify which of the options is a horizontal transverse member directly under the deck plating. • Eliminate any options that are primarily vertical or mainly part of the side shell rather than the deck. • Confirm from your notes or text the standard phrase: "deck plating is supported by deck longitudinals and deck _______".
