Strain - correct answer An alteration in the shape or volume of a soil related to stress. It is calculated as the ratio of the new shape compared to the original shape Effective Stress - correct answer The total amount of stress placed on a soil minus the pore-water pressure Normal Stress - correct answer The component of total stress that acts perpendicular to the plane. Shear stress - correct answer The component of total stress that acts parallel to any point in question. Dila...
