a$)$ Determine the effective and total shear strength parameters and c$,$phi',$c_u,{}_u.$

b$)$ What will be the principal stress difference at failure if UU test is performed on the same clay with cell

pressure equal to $100k\frac{N}{m^2}.$

show me the equations of all the $4$ parameters and their values, show me the drawing of mohr circle and the parameters on the circle, if cell pressure is segma$3=200$ then segma $1$ is $200+440=640???$ I want the mohr circle drawing, post the drawing pleaseProblem

The results of various shear strength tests performed on samples of a saturated intact clay are given below:

i$)$ Drained triaxial test: The cell pressure $($all$-$around pressure$)$ is $200k\frac{N}{m^2}.$ The specimen failed at a

principal stress difference $($deviator stress$)$ of $440k\frac{N}{m^2}.$

ii$)$ Unconfined compression test: The specimen failed at an axial stress of $160k\frac{N}{m^2}.$

On the basis of the above data, using graphical procedure:

a$)$ Determine the effective and total shear strength parameters and $\{$:$c_u,{}_u).$

b$)$ What will be the principal stress difference at failure if UU test is performed on the same clay with cell

pressure equal to $100k\frac{N}{m^2}.$
