Test for Determination of Shear Strength

The term shear strength is often associated with the soil. Shear strength is defined as the resistance to the deformation of soil particles due to the continuous action of shear stress. In short, shear strength is the maximum shear stress that a soil can sustain.

Question

7.2 A specimen of normally consolidated clay (= 28°) was consolidated under a
chamber-confining pressure of 280 kN/m². For a drained test, by how much does
