Factor of Safety given Shear Force in Bishop's Analysis Solution

Follow our step by step solution on how to calculate Factor of Safety given Shear Force in Bishop's Analysis?

FIRST Step Consider the formula

f s = \frac{(c' \cdot l) + (P - (u \cdot l)) \cdot \tan (\frac{φ' \cdot π}{180})}{S}

Next Step Substitute values of Variables

∴

f s = \frac{(4Pa \cdot 9.42m) + (150N - (20Pa \cdot 9.42m)) \cdot \tan (\frac{9.99° \cdot π}{180})}{11.07N}

Next Step Substitute values of Constants

∴

f s = \frac{(4Pa \cdot 9.42m) + (150N - (20Pa \cdot 9.42m)) \cdot \tan (\frac{9.99° \cdot 3.1416}{180})}{11.07N}

Next Step Convert Units

∴

f s = \frac{(4Pa \cdot 9.42m) + (150N - (20Pa \cdot 9.42m)) \cdot \tan (\frac{0.1744rad \cdot 3.1416}{180})}{11.07N}

Next Step Prepare to Evaluate

∴

f s = \frac{(4 \cdot 9.42) + (150 - (20 \cdot 9.42)) \cdot \tan (\frac{0.1744 \cdot 3.1416}{180})}{11.07}

Next Step Evaluate

∴

f s = 3.39323789730528

LAST Step Rounding Answer

∴

f s = 3.3932
