Feature
●The Ugears STEM-lab series allows children to build mechanical models while having fun learning how it works. Recently used "STEM" stands for Science, Technology, Engineering and Math. Ugears new STEM-lab series model is the main idea for STEM, so you can easily learn how it is actually used in a variety of everyday situations, such as gears that are widely used in daily life
●Assemble the tachometer and discover how it works. Model kits come with a QR code to learn guide on mechanics, principles of operation, key characteristics, and formula. It also includes interesting challenges. Dive into an extended reality and see how the tachometer works. Interacts with models through Ugears special AR application
●Tachometer is a device designed to measure the rotation speed of various parts of engines and other mechanisms. Calculates the number of revolutions (RPM) per minute. The tachometer also measures and monitors load restrictions to increase and decrease the RPM so that the engine or mechanism works within the optimal parameter
●Mechanical Addiator is a compact calculator (or additive) that works by moving the gear rack using the stylus included in the kit. You can add and subtract numbers by moving the arrow and the slide rack marked with 0 to 9
●Who invented the tachometer, when is it? Tachometer was invented in 1817 by German engineer DietrichUhlhorn. His invention was a special device to measure centrifugal force. Since 1840, this equipment was used on railroad locomotive and then used for automobiles and all kinds of vehicle transportation
