Artificial intelligence is currently used in numerous scientific and literary sources, including documentaries. Summarizing information material, highlighting the problem of reducing the loss of time when creating new objects, leads to the need to use elements of artificial intelligence. The article discusses the advantages and disadvantages of using artificial intelligence in the design of a cantilever beam under load.

Keywords: artificial intelligence, mechanics, cantilever beam, load, optimal design, resource saving.

The use of anti-friction materials in moving units reduces the likelihood of component wear, increases reliability, service life of parts and mechanisms as a whole. The paper considered the effectiveness of molybdenum coating in the design of oil and gas fittings, namely, an axisymmetric check valve and a control valve. Tests for strength, thickness, microhardness of the coating in the rack and pinion mechanism of oil and gas fittings were carried out.
