Fordulatszáma

Fordulatszáma, often translated as revolutions per minute (RPM) or rotations per minute, is a unit of rotational speed. It quantifies the number of full turns or cycles an object completes around a central axis within one minute. This measurement is fundamental in understanding the operation of many mechanical and electrical devices.

The concept of fordulatszáma is widely used in various fields. In automotive engineering, it indicates the speed at which an engine's crankshaft rotates, directly influencing the vehicle's power output and performance. In industry, motors and machinery often operate at specific fordulatszáma to achieve optimal efficiency and output for tasks such as cutting, grinding, or mixing. In music, it describes the speed of a vinyl record's rotation, affecting the pitch and tempo of the playback.

Measuring fordulatszáma typically involves specialized instruments like tachometers. These devices can be mechanical, optical, or electronic, and they provide a direct reading of the rotational speed. The understanding and control of fordulatszáma are crucial for maintaining the functionality, safety, and efficiency of countless everyday objects and industrial processes.
