Shear Strength given Normal Stress on Slice Solution

Follow our step by step solution on how to calculate Shear Strength given Normal Stress on Slice?

FIRST Step Consider the formula
τ=(c'+(σnormal-u)tan(φ'π180))
Next Step Substitute values of Variables
τ=(4Pa+(15.71Pa-20Pa)tan(9.99°π180))
Next Step Substitute values of Constants
τ=(4Pa+(15.71Pa-20Pa)tan(9.99°3.1416180))
Next Step Convert Units
τ=(4Pa+(15.71Pa-20Pa)tan(0.1744rad3.1416180))
Next Step Prepare to Evaluate
τ=(4+(15.71-20)tan(0.17443.1416180))
Next Step Evaluate
τ=3.98694494047909Pa
LAST Step Rounding Answer
τ=3.9869Pa
