railway RRB JE (CBT I + CBT II) Mock Test 2024 Soil Mechanics and Foundation Engineering Shear Strength
Coulomb's equation for shear strength is given by:
Where, c - unit cohesion
s - shear strength
σ - total stress
ϕ - angle of shearing resistance
1
c = s + σtanϕ
2
s = σ + ctanϕ
3
s = σ - ctanϕ
4
c = s - σtanϕ
