Question

In a Mohr--Coulomb failure criterion, the ratio of the uniaxial compressive strength to the tensile strength is

• A. \(\dfrac{1+\sin\phi}{1-\sin\phi}\)
• B. \(\dfrac{1-\sin\phi}{1+\sin\phi}\)
• C. \(C\left(\dfrac{1-\sin\phi}{1+\sin\phi}\right)\)
• D. \(2C\left(\dfrac{1-\sin\phi}{1+\sin\phi}\right)\)

Hint:

For the Mohr--Coulomb criterion, \[ \boxed{ \frac{\sigma_c}{\sigma_t} = \frac{1+\sin\phi}{1-\sin\phi} } \] where \(\phi\) is the angle of internal friction.

Answer 1

The Correct Option is A
