12.3.1. Introduction of Center of Buoyancy and Archimedes' Principle

Try these first

1. 1.

   What is the Center of Buoyancy?

   Hint

   Think about where the buoyant force acts.

2. 2.

   What principle explains why ships float?

   Hint

   Consider the weight of displaced water.

3. 3.

   What fraction of an iceberg is usually above water?

   • 1/4
   • 1/2
   • 1/8

   Hint

   Think about iceberg sizes compared to their submerged parts.

4. 4.

   Archimedes' Principle states that the buoyant force is equal to the weight of the fluid displaced. Is this True or False?

   • True
   • False

   Hint

   Recall the definition of buoyancy.

5. 5.

   Design a small boat that must float with limited cargo capacity. Calculate the necessary buoyancy to support a given weight and discuss safety features to avoid disaster.

   Hint

   Use the buoyancy formula and consider the cargo's center of gravity.

6. 6.

   Discuss the implications if a buoyant object exceeds its buoyant capacity and how this can lead to accidents. Provide examples from historic events.

   Hint

   Focus on historical examples to illustrate real impacts.
