The wooden plug fitted tightly in the vent of a damaged tank may prevent the tank from __________.

🔍 Key Concepts

• Tank ventilation and structural safety when a tank is damaged • Difference between filling level and free surface effect in a tank • How air trapped in a sealed tank affects its structural behavior

💭 Think About

• Think about what happens if a damaged tank’s vent is tightly plugged and the tank is exposed to outside water pressure – what does the trapped air inside the tank do? • Consider which of the listed problems (filling completely, collapsing, free surface, free surface moments) are related to movement of liquid and which are related to pressure and structural strength. • Ask yourself: does stopping air from escaping mainly affect how the liquid moves inside the tank, or how the tank structure resists outside pressure?

✅ Before You Answer

• Identify which choices (C and D) are really just different ways of describing free surface effect and whether that requires liquid movement inside the tank. • Consider that a vent plug primarily changes how air and pressure behave, not how the surface of liquid can slosh once it’s already inside. • Before choosing, be clear on the difference between a tank not filling up versus a tank losing structural strength and buckling inward.
