Mittepöörduvad

Mittepöörduvad is an Estonian term that translates to "non-turning" or "non-rotating" in English. It is most commonly used in the context of mechanical engineering and physics to describe objects or phenomena that do not exhibit rotational motion.

In mechanics, a non-turning object is one whose orientation in space remains constant or changes only through translation, not rotation. For instance, a rigid body moving in a straight line without spinning is an example of a non-turning object. This concept is fundamental in analyzing linear motion and forces.

The term can also be applied to abstract concepts. In mathematics, a function or transformation might be described as non-turning if it preserves the orientation of points or vectors without introducing rotation.

In everyday language, "mittepöörduvad" might be used to describe anything that is fixed in position and does not spin or revolve. For example, a stationary pillar is non-turning. The specific meaning is highly dependent on the context in which it is used, but the core idea of absence of rotation remains consistent.
