Challenge Problems

Push your limits with challenges.

Question 1

If the required safe load on a concrete pile is calculated using the Engineering News formula as 3000 pounds, but the hammer weight used is only 700 pounds, what adjustments might you need to make in terms of hammer weight or drop height to ensure adequate pile driving?

💡 Hint: Consider how changing the weight versus the height affects the overall energy delivered.

Question 2

Imagine you are onsite and notice that the cushioning material between the hammer and pile has worn out significantly. What immediate actions should you take, and why is it important to replace this material?

💡 Hint: Think about the role of cushioning in absorbing energy.
