The direct shear test is a crucial procedure for assessing the shear strength of dry sand by applying normal loads and shear forces to a specimen in a controlled environment. This method allows for the determination of normal and shear stresses at failure, thereby enabling the calculation of the friction angle associated with the material. Understanding the relationship between relative density and the angle of friction for coarse-grained soil is also essential for effective analysis and application in geotechnical engineering.

The direct shear test is used to measure the shear strength of dry sand by applying normal and shear forces.
Normal and shear stresses at failure are recorded during the test to compute the friction angle.
The relationship between relative density and angle of friction is significant for coarse-grained soils.
