🔍 Key Concepts

• Camber of a deck and what it looks like in profile • How water behaves on a flat vs. slightly curved surface • Primary structural purpose of deck beams vs. secondary benefits

💭 Think About

• Picture rain or shipped seas on a perfectly flat deck—what potential problems can that cause? • If you slightly arch (camber) a beam, what practical effect does that have on anything resting on top of it? • Which choice describes the most direct and obvious benefit of having the deck surface sloping slightly from the centerline to the sides?

✅ Before You Answer

• Visualize the shape of a cambered deck: higher at the centerline, lower at the sides • Ask which option deals with what happens to water on deck, not just internal stresses in the steel • Eliminate options that talk about effects that are possible but not the main design reason for camber
