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 of cams & cranks such as a fishing crane, an oil pump, a moving figure, a moving bridge, a sewing machine and a flying eagle. 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 challenge your newly acquired knowledge!Build an oil pumpConstruct a working model of an oil pump and find outhow different simple machines work together withcams. Are you up to oil drilling? Turn the crank and seehow everything changes position in front of your eyes.Build an eagle with flapping wingsThis model of a flying eagle is designed to flap its wings by the use of the cam and crank mechanisms. Turn the crank and discover how rotational motion becomes linear. Observe how the flapping motion is produced by the employment of linkages.Build a fishing craneConstruct a unique fishing crane and learn how the crank helps set this device into motion. Compare your model with a real life one and find out the capabilities of a crank when connected to a string for lifting heavy loads.Build a moving figureBuild a model of a moving figure that uses cams and learn how you can change the direction of motion and assemble 2 different types of cams. Play with this model and discover the properties of cams.
