"Get the MECHANICS: Cams & Cranks set and learn how you can transmit power using Cams and Cranks and how they can be used to convert reciprocal to linear motion. Discover how these mechanisms are crucial elements of many machines even though they are not considered as “Simple Machines”. Build 8 working models such as a fishing crane, an oil pump, a moving figure, a moving bridge, a sewing machine and a flying eagle. 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. *34-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. 8 working models to build! Conduct thorough experiments and discover: - how the handle's position affects force and speed; - how the crank's position affects force and speed; - how to switch between different types of motion by using cams. *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. Product Material: ABS Plastic and TPE"
