Product Description
Stem Mechanics: Gears & Worm Drives
Get the MECHANICS: 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 an experimental crane, a gearbox, a carousel, a helicopter, a screw press and a crane with a rotating arm.
Key Features:
*Snap-fit connectivity in any direction and angle.
*Extraction tool for easy disassembly.
*Easy-to-follow building instructions.
*All parts are non-toxic and made to last. Vibrant coloured parts.
*Printed instruction are included.
*The Discovering STEM series introduces children into the world of STEM disciplines (Science – Technology – Engineering and Mathematics) through a completely new learning approach! Boys and girls can construct exciting models while learning scientific and technological subjects and doing experiments in each theme.
*46-page booklet with theory, experimental activities, quiz and building instructions! Full colour images, drawings and interesting facts. Thought provoking building challenges and exercises. Provision to write, note results and draw conclusions. Various gears of high precision for changing speed! 12 working models to build! Conduct thorough experiments and discover: - how the gear's diameter affects force and speed; - how to calculate gear ratio, even for complex assemblies; - how to use gears to change the direction and plane of motion; - how to calculate the mechanical advantage of a screw; - what a worm drive is and how to use a ratchet mechanism.
*All models are available as interactive 3D instructions viewed either from a PC or from smartphones and tablets through the ENGINO 3D Viewer app, downloadable for free in Android, Apple (iOs) and Windows mobile operating systems.
