Question:medium

Shear strength of a rock joint is not dependent on

Show Hint

For a rock joint, \[ \boxed{ \tau=c+\sigma_n\tan\phi. } \] Thus, shear strength depends on cohesion, normal stress, and friction angle—not on the applied shear stress.

Updated On: Jul 14, 2026

Applied normal stress
Applied shear stress
Friction angle of the joint plane
Cohesion of the joint plane

Show Solution

The Correct Option is B
