The measured strength parameter of a normally consolidated clay soil was found to be 30 degrees. Determine the major principal stress (in kPa) from a Mohr circle at failure if the sample fails due to shear at 60 kPa.

Hint: draw the Mohr-Coulomb failure envelope and associated Mohr circle at the failure to estimate (calculate) the major principle stress from your drawing.
