Learn how pulley drives can be used to transfer force with reduced friction. Pulleys have been used for thousands of years and are essential components of complex machines in modern times. Build eight working models, such as a material lift, a stationary bike, a crane bridge, a blender, a construction crane, and a windmill. You can find easy-to-follow building instructions for all models either online or in the booklet included. The booklet provides detailed explanations of the different scientific principles applied, and incorporates innovative experimental activities for hands-on learning. A Quiz section is also available to help review your newly acquired knowledge! Conduct thorough experiments to discover what you learned about: — how a compound pulley system works; — how to change the direction of motion of a pulley system; — how a pulley’s size affects force and speed
