Q75
In the Mohr-Coulomb failure criterion, the shear strength of rock is expressed as:
A.
c + ?
B.
? + ?
C.
? - c
D.
c + ? tan ?
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
The Mohr-Coulomb equation for shear strength is: ? = c + ? tan ?, where:? = shear strengthc = cohesion? = normal stress? = angle of internal friction
