Depth of Footing given Angle of Inclination from Horizontal Solution

Follow our step by step solution on how to calculate Depth of Footing given Angle of Inclination from Horizontal?

FIRST Step Consider the formula

D = \frac{q f}{γ \cdot {(\tan (\frac{i \cdot π}{180}))}^{4}}

Next Step Substitute values of Variables

∴

D = \frac{0.03kPa}{18kN/m³ \cdot {(\tan (\frac{64° \cdot π}{180}))}^{4}}

Next Step Substitute values of Constants

∴

D = \frac{0.03kPa}{18kN/m³ \cdot {(\tan (\frac{64° \cdot 3.1416}{180}))}^{4}}

Next Step Convert Units

∴

D = \frac{0.03kPa}{18000N/m³ \cdot {(\tan (\frac{1.117rad \cdot 3.1416}{180}))}^{4}}

Next Step Prepare to Evaluate

∴

D = \frac{0.03}{18000 \cdot {(\tan (\frac{1.117 \cdot 3.1416}{180}))}^{4}}

Next Step Evaluate

∴

D = 11.5316063177005m

LAST Step Rounding Answer

∴

D = 11.5316m
