A composite structure apparatus for determining the interaction forces and reactions RIGID FILLER AND weightless rod

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.; The task to be solved by the proposed utility model, is to reduce the material consumption for the manufacture of a composite structure due to unification of the constituent elements.; The technical result is achieved in that in the composite constructions of devices for determining the interaction forces and reactions tight seal and weightless rod mounted on the frame and comprising a left and right portion, the left and right sides are made up of structural elements, rods and interconnected internal rotational hinge, wherein one rod to the frame portion associated rigid composite structure embedded, and other parts of the rod of composite construction - weightless rod, according to the proposed utility meters put, the composite structure is a set of standardized building blocks arranged to build unified elements: a frame, left and right supports made removable, structural elements, rods, made as a set of elements consisting of rectilinear, polygonal, L-shaped, T-shaped, H-shaped bars mounted on the supports, wherein the unified frame comprises upper and lower base, left and right side plates, when the hard bond which forms a closed hard mentioned rectangular contour, wherein the frame is provided with a removable corner brace adapted to be rigidly fixed in the corners of a closed rectangular loop frame, removable inclined abutment adapted to be fixed to the upper or lower bases, left or right side racks and placed on its inclined plane bottom hinge weightless rod and removable terminal adapted to its displacement and rigid fastening, or to the upper or lower bases of the frame.; Such a composite structure execution devices for determining the interaction forces and reactions tight seal weightless rod and thus significantly reduce the flow of material (metal) and the means for their manufacture due to unification of the constituent elements. 10 yl.
