This instrument is primarily used to determine the shear strength of soil. Typically, four soil samples are tested. Each sample is subjected to different vertical pressures (selectable from 400 kPa, 300 kPa, 200 kPa, 100 kPa, and 50 kPa), and a horizontal force is applied to induce shear failure. The shear stress at failure is measured, and the shear strength parameters of the soil—the angle of internal friction and cohesion—are determined according to Coulomb’s law.
