Kiertonopeisiin
Kiertonopeisiin, often translated as revolutions per minute (RPM), is a unit of rotational speed, measuring how many times an object rotates in one minute. It is commonly used to describe the speed of rotating machinery such as engines, motors, hard drives, and washing machine drums. For example, a car engine might operate at 2000 RPM, meaning its crankshaft rotates 2,000 times every minute. Similarly, a hard drive might spin at 7200 RPM, indicating its platters complete 7,200 rotations in sixty seconds.
The concept of kiertonopeisiin is fundamental in various engineering disciplines. In internal combustion engines, higher RPM
