Abstract
This article has developed a mathematical model that allows to determine the amplitude-frequency and phase-frequency characteristics of the floating bridge of the hinge-cut system. At present, intensive construction of floating bridges is being carried out all over the world. This is due, above all, to the low cost of building the floating bridges, as well as the high technological and fast construction of the floating bridges. From the moment of gaining independ-ence to the present time, in Ukraine, the construction of floating bridges is not performed for a number of reasons, although their construction would save the state considerable material and financial resources, and also improved the network of road communications. The complete absence of theoretical studies and scientific developments in the theme of floating bridges in recent years has led to the loss of the skills of designing and building floating bridges in Ukraine.

INFLUENCE OF CARBON FIBER ON TRIBOLOGICAL PROPERTIES OF PEEK
Polyetheretherketones (PEEK) are aromatic polymers with monomolecular chains built of phenylene rings, the carbonyl groups and oxygen atoms. PEEK has a unique complex of operational properties (deformation heat resistanc...
ABOUT DYNAMIC DEFLECTIONS OF WIRES OF ELECTRIC TRANSPORT
It is well known that a moving load causes a greater deflection on the cable and therefore a higher voltage than a static load. This dynamic effect of moving loads on a cable or rope is of great practical importance. In...
