STAND FOR EXPERIMENTAL RESEARCH IN VIEW OF FRICTION FORCES REST IN CONNECTION 'brake pads drum'

摘要

The invention relates to laboratory equipment and can be used in teaching laboratories on Theoretical and Applied Mechanics of technical universities, colleges and technical schools.; A well-known stand has constant size rod and constant position of its legs, which does not allow to carry out research to identify the dependence of forces on the stand units sizes to fit the static friction.; The proposed stand is provided with a carrier pivotally connected to the frame in the swivel drum to the frame, the main core of the carrier is parallel to the rod and rigidly connected with its guides, the left part of the rod guide and part of the rod located between the guides are telescopic, the outer rods telescopic joints made with terminals at the ends directed to the right, the right end of the main rod carrier terminal connected to the carriage to move it along a circular guide groove Art Anya, the middle line which is an arc of a circle whose center coincides with the geometric axis of rotational hinges drums, and rigidly fixing a carriage by means of threaded fasteners to the frame.; This allows students to carry out research and to raise their level of engineering education in the first year of theoretical mechanics. 1 Fig.
