1. Calculate the density of the soil specimen from the mass of soil and the volume of the shear box.

2. Convert the dial readings to the appropriate displacement and load units by multiplying with respective least counts.

3. Calculate shear strains by dividing horizontal displacements with the specimen length, and obtain shear stresses by dividing horizontal shear forces with the shear area.

4. Plot the shear stress versus horizontal displacement. Read the maximum value of shear stress if failure has occurred, otherwise read the shear stress at 20% shear strain.

5. Plot the maximum shear stress versus the corresponding normal stress for each test, draw the Mohr-Coulomb failure envelope, and determine the cohesion and the angle of shearing resistance of the soil.

Cohesion (kg/cm²) =
Angle of shearing resistance (°) =
