Challenge Problems

Push your limits with challenges.

Question 1

A hammer weighs 60 pounds and falls from a height of 8 feet. Calculate the blow energy produced during driving. What are the implications of this energy level for safety and efficiency?

💡 Hint: Ensure to double-check the formula for energy conversion.

Question 2

Given a pile with a safe load determined to be 150 pounds, how much weight must a hammer have if the average penetration per blow is 4 inches and the height of fall is 10 feet? Use the Engineering News formula to find the solution.

💡 Hint: Be careful with unit conversions and simplifying.
