Height of Drop given Allowable Load for Drop Hammer Driven Piles Solution

Follow our step by step solution on how to calculate Height of Drop given Allowable Load for Drop Hammer Driven Piles?

FIRST Step Consider the formula

H d = \frac{P a \cdot (p + 1)}{2 \cdot W h}

Next Step Substitute values of Variables

∴

H d = \frac{12.09kg \cdot (2mm + 1)}{2 \cdot 20.19kg}

Next Step Convert Units

∴

H d = \frac{12.09kg \cdot (0.002m + 1)}{2 \cdot 20.19kg}

Next Step Prepare to Evaluate

∴

H d = \frac{12.09 \cdot (0.002 + 1)}{2 \cdot 20.19}

Next Step Evaluate

∴

H d = 0.300004457652303m

LAST Step Rounding Answer

∴

H d = 0.3m
