kääntökulma

Kääntökulma is a Finnish term that translates to "turning angle" or "angle of rotation." It is a concept primarily used in geometry and mechanics, referring to the angle through which a point, line, or object is rotated around a central point or axis.

In geometry, the kääntökulma describes the degree of rotation needed to move a shape or a point from one position to another. This rotation can be clockwise or counterclockwise, and it is measured in degrees or radians. For example, rotating a square by 90 degrees would change its orientation relative to its original position. The kääntökulma is a fundamental concept in understanding transformations, such as rotations, translations, and reflections, which are used to analyze geometric figures.

In mechanics, kääntökulma is used to describe the angular displacement of a rotating body. This could refer to the rotation of a wheel, a gear, or any other component that undergoes circular motion. The kääntökulma indicates how much a component has turned over a specific period or in response to a force. For instance, in engine design, the kääntökulma of the crankshaft is crucial for understanding the timing and power delivery of the engine. The measurement of kääntökulma is essential for calculating angular velocity, angular acceleration, and torque.
