FIELD: physics.
SUBSTANCE: method of measuring relative shear resistance of an elementary layer inside granular material moving together with a bogie under the action of a falling weight. The granular material is divided into two parts by a horizontal plate on the level of said elementary layer. The top part is put into a box which is connected by a thread to the recording device of a dynamometer, and the bottom part is moved relative the top part on a bogie. The shear resistance force is measured and continuously recorded on paper in a function of the shear path, and the weight of the empty box is considered as additional height of the granular material.
EFFECT: ensuring high accuracy of measuring shear resistance force of granular material without violating its structure and conditions in which it lies.
