This article presents a method for quickly testing the strength of plastic gears, focusing on using 3D printing with continuous fiber reinforcement to improve durability. A model gear was designed and tested wear fatigue under different loads. The tests showed that reinforcing gears carbon increases their strength, especially moderate However, teeth may fail higher study also emphasizes need automated efficiency accuracy.

The article analyzes the advantages and disadvantages of three-layer orthotropic slabs. It is shown that when developing design such slabs, it necessary to work out technology connecting elements in structure. use laser welding for connections effective small thicknesses. Such sheet with a thickness 12–50 mm has number limitations, strength characteristics joints have not been sufficiently studied. Therefore, slabs large load-bearing capacity, advisable steel slab using electric arc welding....

The paper analyzes the advantages and disadvantages of three-layer orthotropic slabs. It is shown that when developing design such slabs, it necessary to work out technology for connecting elements within structure. use laser welding effective joining small thicknesses. Such sheet with a thickness 12–50 mm has number limitations, strength characteristics joints have not been sufficiently studied. Therefore, in manufacture heavy-duty structures, steel plates are often used; connected each...

The article deals with the creative ways in which a number of Native American authors offer characters and various approaches readers to discovering "the center", becomes rich diverse experience that can also reveal writer's deep self-awareness as storyteller. These centers, are critical development character, image, plot, determine overall structure concept story. Being result self-reflectiveness narrators controlling whole narrative concept, such centers have precedents traditional systems poetics.

The article discusses the problem of using speech redundancy as a means determining level communicative competence in Russian foreign language. In our research, issue is considered from point view speaker and listener should be taken into account both during day-to-day communication while communicating academic settings. On one hand, when facts are explained repeatedly, detailed way, they lose their informativity. other facilitates more adequate understanding. use by enables us to draw...
