PROBLEM $03$:

The figure below summarizes the results of three CU tests done on samples obtained from a site in San Marcos, TX near Blanco River. The geotechnical engineer, Emma, has still not done sieve analysis and Atterberg's limits on the soils and is not sure about the type of soil there. She ran three CU tests and plotted the deviatoric stress variation as function of axial strain below. You are asked to determine the deviatoric stresses at $2\%$ axial strain and perform all necessary calculations as such.

Fill in the table below:
