Follow our step by step solution on how to calculate Unit Weight of Soil under Strip Footing for General Shear Failure?

FIRST Step Consider the formula

γ = \frac{q nu - ((C \cdot N c) + (σ s \cdot (N q - 1)))}{0.5 \cdot B \cdot N γ}

Next Step Substitute values of Variables

∴

γ = \frac{87kN/m² - ((1.27kPa \cdot 9) + (45.9kN/m² \cdot (2.01 - 1)))}{0.5 \cdot 2m \cdot 1.6}

Next Step Convert Units

∴

γ = \frac{87000Pa - ((1270Pa \cdot 9) + (45900Pa \cdot (2.01 - 1)))}{0.5 \cdot 2m \cdot 1.6}

Next Step Prepare to Evaluate

∴

γ = \frac{87000 - ((1270 \cdot 9) + (45900 \cdot (2.01 - 1)))}{0.5 \cdot 2 \cdot 1.6}

Next Step Evaluate

∴

γ = 18256.875N/m³

Next Step Convert to Output's Unit

∴

γ = 18.256875kN/m³

LAST Step Rounding Answer

∴

γ = 18.2569kN/m³
