What is meant by the shear strength of soils? O A. Shear strength of a soil is its internal resistance to deformations. B. Shear strength of a soil is its iexternal resistance to shearing stresses. O C. Shear strength of a soil is its internal resistance to shearing strains. O D. Shear strength of a soil is its internal resistance to shearing stresses. QUESTION 14 Some soils show a peak shear strength? O A. These soils are generally firm (e.g. normally consolidated clays) and the confining stresses are large enough to suppress O B. These soils are generally dense and are large enough to O C. These soils are generally dense (e.g. dense sands and overconsolidated clays) and the confining stresses are not large enough to suppress dilation. O D. These soils are generally LOOSE (e g. loose sands and underconsolidated clays) and the confining stresses are large enough to suppress dilation. suppress dilation. dilation.
