A tachometer is a device designed to measure the rotational speed of various parts in engines and other mechanisms. It calculates revolutions per minute (RPM). The tachometer also measures and monitors load limits, in order to decrease or increase RPM so that the engine or mechanism runs within its optimal parameters.
The tachometer was invented by the German engineer Dietrich Uhlhorn in 1817. His invention was a special device that measured centrifugal force. From 1840 on, this device has been used in railway locomotives, and later in cars and all manner of vehicular transport.
The tachometer is used in mechanisms where it is necessary to accurately track RPM to avoid the negative consequences of overloads. Savvy motorists use tachometers to know when to shift gears (in cars with manual transmissions) and to control the load on the engine, thereby increasing the operating life of their vehicles.

#WHY WE LOVE UGEARS?
We love Ugears for its beauty and challenge. Each of the models is a mechanical masterpiece that you get to put together yourself. For anyone who loves to make models, design or just tinker, this will make you want to do more. Patience and perserverance are required skills, not so much age. Although I would recommend that for kids under 13 years that they be helped out by and adult. Now just up to you to choose your model. Good Luck!
