The effective stress friction angle of a saturated, cohesion less soil is 38°. The ratio of shear stress to normal effective stress on the failure plane is
-
- 0.781
- 0.616
- 0.488
- 0.438
Correct Option: A
τ = C + s tan Φ .
C = 0 (cohesion less soil)
Φ = 38°
τ = σ tan 38°
| = | ||||
| Normal stress | σ |
= tan 38° = 0.781
