It demonstrates how the two drive wheels mounted on the same axle can rotate at a different rate and can thus cover a different distance. This mechanical toy is a miniature version of the main part of the transmission mechanism of a car. It improves its maneuverability and performance. Similar to other UGEARS construction kits for adults and children, this educational toy has an iconic design and it moves\u003cbr\u003eThe TACHOMETER 3D puzzle from UGEARS' STEM Lab collection is a fully operational DIY wooden model of a tachometer, ready for you to assemble. When the handle is rotated, movement is transmitted through a reducer, increasing the RPM and displacing twin weights in the centrifugal unit.\u003cbr\u003eThe GEARBOX model kit is a miniature of a car transmission mechanism that transfers torque from the engine's crankshaft to the wheels. This mechanical toy features one reverse gear and three forward gears meaning layshaft and gears rotate with increasing speed. Like other UGears construction kits for adults and children, this educational toy has an iconic design and it moves.\u003cbr\u003eThe VARIATOR mechanical model is a device that transfers and adjusts engine torque by changing the gear ratio. This wooden construction kit reveals the mystery and science behind continuously variable transmission (CVT). Use this 3D puzzle to learn about one of a car's essential mechanisms without basting yourself in machine oil!\u003cbr\u003eEverything is in the box: Similar to other UGEARS building kits for adults and 3D puzzles for kids, putting together STEM toys is fun and simple: Everything you need to build, learn, and discover comes in a box. Interact with mechanical models: All STEM model building kits for adults pair with the UGEARS augmented reality app. Point your tablet or mobile phone at your fully assembled 3D wooden puzzle, and the app will show you various applications of the mechanism you've just built.\u003cbr\u003e\u003cbr\u003e\u003cp\u003e A STEM series set “Car Mechanisms” includes 4 models from educational STEM Lab series by Ugears – Gearbox, Differential, Tachometer and Variator. These wooden mechanical DIY models help learn how the mechanisms work. Great for kids and adults, especially schoolchildren and students! Each model comes with a QRcode that links to the study guide about the mechanism. The study guide explainshow the mechanism functions, its main characteristics, and formulas. It also includes interesting tasks and assignments. Also, you will find a QRcode to the AR app to interact with the assembled model. The Gearbox is a reducer that provides speed and torque conversions from a motor to the driving wheels. Model has I, II, III, Reverse and N (idle) gear like a real 4-speed Manual Gearbox. The Differential makes entering and going out of turns easier for the car driver. The Tachometer measures the rotational speed of various parts in engines and other mechanisms. The Variator is a device that transfers and adjusts the engine torque by changing the ratio of gears. Connect the Tachometer to the Variator, creating a new mechanism that demonstrates the direct relationship between the transmission ratio of a gearbox, and rotational speed. \u003c\/p\u003e\u003cbr\u003eToys \u0026amp; Games Puzzles Brain Teasers","brand":"Bella","offers":[{"title":"Default Title","offer_id":56226240069924,"sku":"P353529334969013890","price":21.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1022\/4540\/0868\/files\/33cf2ab330782058e66e011f0b6b64aa1188c472f3e262c8cc831a318865bca2.jpg?v=1788850382","url":"https:\/\/www.sqqlbhhlcp.shop\/products\/ugears-set-of-4-stem-lab-models-car-mechanisms-differential-tachometer-gearbox-variator-3d-puzzles","provider":"Bella","version":"1.0","type":"link"}
