tengelyi
Tengelyi is a term that can refer to several related concepts, primarily in mathematics and physics, all revolving around the idea of an axis or central line. In geometry, a tengelyi refers to an axis, which is a line of symmetry or a reference line around which other elements are arranged or measured. For instance, a cylinder has a tengelyi that runs through its center, and a circle's tengelyi is its diameter.
In mechanics and engineering, the term is often used to describe the rotational axis of a moving
The concept of a tengelyi can also be extended to coordinate systems. In a Cartesian coordinate system,
