Description

There are arched trusses made in the form of a two-joint, once statically indeterminate arch.

A distinctive feature of the truss, according to goblins, is that the truss nodes are connected by one-way connections, as a result of which jforyT pivot rods perceive only the single sign (with; cate or stretch) and origin in one of them, the EFFORT of the mark on which his work is impossible, it is turned off from the radiota, about 1) the third hinge. The arched truss is transformed by an irri from a two-ball into a three-fold, which ensures the further stability of the truss and the work of the remaining rods on a seated incense mark.

The presence of a sign of interchangeable forces in the rods allows the nodal connections to be worn out and to use fully the bearing force for compression or expansion of the material of the rods.
