A pile hammer with a weight of 6000 pounds drops from a height of 10 feet, and the average penetration is 0.55 feet. Calculate the safe load on the pile using the Engineering News Formula.
💡 Hint: Use the formula properly and convert feet to inches if necessary.
Discuss why heavier hammers with lower drop heights are preferred in concrete pile driving over lighter hammers with higher drop heights.
💡 Hint: Consider the effects of impact force on brittle materials.
