Question 1 of 27070

Increasing the free surface of a confined liquid has the effect of raising the __________.

🔍 Key Concepts

• free surface effect and how it impacts stability • relationship between KG (center of gravity height), GM (metacentric height), and apparent or virtual G when liquids shift • difference between actual structural points (like metacenter) and calculated/virtual values

💭 Think About

• When a free surface gets larger, does the vessel become more or less stable? How would that change GM (metacentric height)? • Does free surface change the ship’s actual weight distribution, or does it make the center of gravity act as if it moved? What term describes that ‘as if’ position? • Which of the choices is a value that can increase even though the actual geometry of the ship hasn’t changed?

✅ Before You Answer

• Verify which quantities are geometric properties of the hull (do not change with liquid motion alone). • Check which option refers to a virtual or ‘apparent’ position related to the center of gravity. • Confirm that free surface reduces stability (GM), so eliminate any option that would directly indicate an increase in true stability.
