Please complete $8\mathrm{.}16$ but with applied shear stress at $5$ psi, c $=6$ psi, and phi $=28$ degrees. Thank you kindly!!

$8\mathrm{.}16$ Figure P$8\mathrm{.}16$ shows stresses at a point.

a$.$ Draw the Mohr circle for this point, showing the pole location.

b$.$ What are the stresses acting on a horizontal plane passing through this point?

c$.$ The cohesion intercept for this soil is $c=5,$ and the friction angle is $=30.$ If the major principal stress remains the same, what would the minor principal stress have to be to cause failure?
