FIELD: testing equipment.
SUBSTANCE: lever installation is made by welding metal brackets to the metal stand, oval holes are cut out at the ends of the brackets and shafts with pulleys are installed, the linkage is rigidly fixed in the base. A test specimen is made with a pair of forces fixed at one end of the rod of arm of couple, fixed with a yoke, the other end of the specimen is clamped in the device for pinching the beam moment. To the rod of the arm of couple, cables are attached, and horizontal cables are hung on cables routed through pulleys, onto which weights are laid to create a concentrated bending moment.
EFFECT: load-carrying capacity of the beams is determined for the concentrated bending moment, the constancy of the acting moment in time is ensured with deformations of the test elements.
