🔍 Key Concepts

• Naval architecture symbols commonly used on hydrostatic curves and cross curves of stability • How the center of buoyancy (B) is typically denoted in formulas and diagrams • The difference between displacement (Δ), center of buoyancy (B), and baseline on ship plans

💭 Think About

• Look at symbol #1 and relate it to which quantity is almost always shown by the Greek capital delta in stability work, then compare that to symbol #2 • Ask yourself which choice would logically be represented by a symbol that clearly includes the letter B in it • Consider which of the options refers to a point or location in the vessel, versus those that refer to a distance, line, or total weight

✅ Before You Answer

• Make sure you can match Δ (triangle) with the appropriate hydrostatic quantity; then you can eliminate that option for symbol #2 • Identify which answer choice describes a single point in space inside the ship, not a dimension or line • Confirm that the symbol in box #2 visually contains the letter B, and link that to the correct naval-architecture term using B
