The parameters of a soil are λ = 0.2, κ = 0.04, f¢cs =30°, eo = 1.08 at p¢o = 80 kPa and R_o = 7. If the soil were to be loaded so that its total stress path q/p = 2.5, predict the following.

Initial yield stresses, under undrained condition.
Excess pore water pressure at yield for undrained condition.
The undrained shear strength at initial yield.
A stress path along which the soil may not fail in drained condition.
