Layer Coefficient of Base Course given Structural Number Solution

Follow our step by step solution on how to calculate Layer Coefficient of Base Course given Structural Number?

FIRST Step Consider the formula

a n = \frac{SN 2}{T a \cdot M n}

Next Step Substitute values of Variables

∴

a n = \frac{150.5mm}{1200mm \cdot 0.25}

Next Step Convert Units

∴

a n = \frac{0.1505m}{1.2m \cdot 0.25}

Next Step Prepare to Evaluate

∴

a n = \frac{0.1505}{1.2 \cdot 0.25}

Next Step Evaluate

∴

a n = 0.501666666666667

LAST Step Rounding Answer

∴

a n = 0.5017
