   Hint

   Think about the mechanism of air movement.

2. 2.

   What kind of energy does a diesel hammer primarily use?

   Hint

   Consider the fuel type.

3. 3.

   What is the main power source in a double acting steam hammer?

   • Electric
   • Steam
   • Hydraulic

   Hint

5. 5.

   If a construction site needs to drive piles into hard clay, which pile driver would be appropriate? Justify your answer based on the mechanisms discussed.

   Hint

   Consider the type of soil and the energy source of the hammer.

6. 6.

   Design a pile driving operation where resonance is incorporated. Explain how you would determine the natural frequency and avoid structural damages.

   Hint

   Relate the concept of natural frequencies to real-world applications.
