(Provide the answer to nearest one decimal point) A triaxial compression test was conducted on a saturated soil sample to determine its shear strength parameters: effective cohesion (C') and effective friction angle (Φ'). The confining pressure used during the test was 30 psi. The deviator stress on the sample at the time of failure was 40 psi. The porewater pressure measured at the time of failure was 5 psi.a) The figure below shows the stress conditions on the sample at the time of failure. Provide the values of total stresses, σ₁ and σ₃ on the sample.![Illustration of a cylindrical sample under stress.

3. At a different location in the Chesapeake, the same u-=4.4 cm/s and z,=3.1 cm were measured. At this new location, at 1 m above the bed, the Reynolds stress was measured to be u w' =-17.8 cm²/s² and the flux Richardson number was 0.23. First compute the velocity gradient at 1 meter above the bed using the logarithmic distribution and then determine the buoyancy flux ( w'p') at this location. Is the water column stably stratified?
