Question

the effective stress friction angle of a saturated cohesionless soil is 25 the ratio of

Answer 1

Thanks for this question. Please find the answer below:

Keeping in view that; the effective stress friction angle of a saturated cohesionless soil is 25.

The ratio of shear stress to normal effective stress on the failure plane is 0.781.

Answer 2

Explanation:

angle = tan -1 (shearstree/normal stress). Therefore ratio of shear stress to normal effective stress on the failure plane is= tan 250=0.466. Keeping in view that; the effective stress friction angle of a saturated cohesionless soil is 25.
