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

Following data are given for a direct shear test conducted on dry silty sand:
Specimen dimensions: diameter = 71 mm; height = 25 mm
Normal stress: 150 kN/m2
Shear force at failure: 276 N
