STEM Mechanics - Gears & Worm Drives

DESCRIPTION

Gears & Worm Drives set and learn how Gears can easily reduce or increase speed, change force or transfer motion from one position to another. Discover how Worm drives are used to greatly reduce rotational speed and how screws can convert rotational motion to linear, while greatly increasing force. Build 12 working models such as experimental crane, gearbox, carousel, helicopter, screw press, crane with a rotating arm
