However, with the advent of aviation, this type of friction is becoming less and less relevant, and in aviation, screwless tension and rotational motion is most effective.Surface friction is widely used in radio electronics and technology of aircraft and helicopters, where flight safety depends on the reliability of operation, and hence the service life of electrical equipment. In helicopter construction and aircraft technology, there is the so-called tension friction: the bearing surfaces transfer part of the energy to the particles of the carrier material. The highest speed of movement of parts relative to the supporting structures is 10 m/s. With surface friction, parts from the bearing elements of the ship’s hull under the action of their own weight slowly move along its longitudinal axis. In shipbuilding, surface friction (the principle of all mechanisms) and rolling friction are used, which is characterized by the difference in the final dimensions of the parts that act on each other in the system. It is customary to distinguish between solid sliding friction (or non-sloping, in the absence of rolling) and slope rolling: There are the following main types of friction based on differences in material, surface condition and displacement: Latin and Greek terms are not clearly defined, as these terms have scientific and medical significance.įriction between solid bodies is called sliding friction.
