engineering recuitment NHPC JE & THDC JE 2023 Mock Test Soil Mechanics and Foundation Engineering Shear Strength
When c is cohesion, σ is the applied normal stress ϕ is the angle of internal friction, the shear strength of the soil τ will be equal to
1
τ = c - σ tan ϕ
2
τ = c + σ tan ϕ
3
τ = σ + c tan ϕ
4
τ = σ - c tan ϕ
