Please answer the following questions: (1) Soil samples from this site are mainly cohesionless sand (e'= 0). A consolidated undrained triaxial test was conducted on one of the samples at a confining pressure o, = 100 kN/m. Failure occurred when the major principal stress a = 200 kN/m with a pore water pressure u = 50 kN/m². Deternine the effective stress angle of friction, ' of the soil accordingly.

Below this is a fairly soft blue-gray silty-clay with an average water content of 30 %. The boring was terminated at 16 m below the ground surface when fairly stiff silty clay was encountered. Make reasonable assumptions as to soil properties and calculate the total, water, and effective stresses at 3, 6, 11, and 16 m below the ground surface.
