Etymology:
The word "tacho" originates from the Greek word "tachos," meaning "swiftness" or "speed."
Meaning and Origin:
A "tacho" is a device that measures either the rotational speed of a shaft or the speed of a vehicle, such as a car or motorcycle.
The tachometer was first invented in 1791 by an English engineer named James Watt. Watt's tachometer used a centrifugal governor to measure the speed of a steam engine. Over time, tachometers have evolved to become more sophisticated and accurate, with many modern tachometers using electronic sensors to measure speed.
Today, tachometers are widely used in various applications, including:
