S.T.E.M Mechanics – Cams & Cranks




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


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!

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


34-page booklet with theory, experimental activities, quiz and building instructions
