7.9 A specimen of soil was collected from a depth of 12 m in a deposit of clay. The ground water table coincides with the ground surface. For the soil, LL= 68, PL = 29, and Yat = 17.8 kN/m³. Estimate the undrained shear strength S of this clay for the following cases. (a) If the clay is normally consolidated. (b) If the preconsolidation pressure is 191kN/m².
