Challenge Problems

Push your limits with challenges.

Question 1

A construction team is attempting to drive a concrete pile using a hammer weighing 200 pounds and a drop height of 3 feet. Calculate the hammer energy and evaluate the potential impact stress it could exert on the pile. Discuss how this might differ from using a lighter hammer.

💡 Hint: Use the energy formula and consider the relationship with pile condition.

Question 2

If soil type conditions change, what adjustments should the team consider when selecting hammer and cushioning? Provide a rationale for your proposed changes.

💡 Hint: Think about soil impacts on energy needs and structural support.
