Effective Stress on Slice Solution

Follow our step by step solution on how to calculate Effective Stress on Slice?

FIRST Step Consider the formula

σ' = (\frac{P}{l}) - ΣU

Next Step Substitute values of Variables

∴

σ' = (\frac{150N}{9.42m}) - 2N

Next Step Prepare to Evaluate

∴

σ' = (\frac{150}{9.42}) - 2

Next Step Evaluate

∴

σ' = 13.9235668789809Pa

LAST Step Rounding Answer

∴

σ' = 13.9236Pa
