The results of two triaxial tests on a soil are as follows: -Specimen I: σ3 = 50 kPa and (σ1 - σ3)f = 120 kPa -Specimen II: σ3 = 130 kPa and (σ1 - σ3)f = 200 kPa a) Determine the shear strength parameters c and ɸ. b) Draw the Mohr's circle for both specimens and the Mohr-Coulomb failure criterion. Make sure the drawing shows σ1f and σ3f for both specimens and c and ɸ.
