摘要：
FIELD: testing equipment.SUBSTANCE: invention relates to the field of mechanical testing of materials, in particular to the determination of the friction coefficient between specimens. One of the specimens, fixed immovably, is made with a working surface having a rectilinear or concave circular shape. Rectilinear guide element is placed at a certain distance from the fixed specimen. Movable specimen is made with two working edges, oppositely located on its diagonal having the length of d. Possibility of moving the movable specimen along the working surface of the fixed specimen is provided. Movable specimen is set so that one of its working edges is in contact with the fixed specimen, and the second, when touching the guide element, is located with such lagging from the first edge in the direction of travel, that a certain angle ϕ is formed between the diagonal of the movable specimen and the perpendicular to the working surface of the fixed specimen or to the line tangential to the circular working surface
