12.3. Summary of Key Concepts

Try these first

1. 1.

   What is buoyancy?

   Hint

   Think about why ships float.

2. 2.

   What percentage of an iceberg is visible above water?

   Hint

   Consider the hidden part of the iceberg.

3. 3.

   What is the primary cause of instability in an iceberg?

   • Underwater melting
   • Weather conditions
   • Ice formation

   Hint

   Consider what affects buoyancy.

4. 4.

   True or False: The Titanic had sufficient technology to navigate icebergs.

   • True
   • False

   Hint

   Think about the historical context.

5. 5.

   Given a floating ship's dimensions, calculate its metacentric height and assess its stability.

   Hint

   Reference the definitions of buoyancy and stability concepts.

6. 6.

   Analyze a case study of a ship design that failed due to underestimating iceberg risks. What engineering principles could have been applied to prevent this?

   Hint

   Refer to modern technologies and reflect on past lessons from disasters.
