Engineering Fundamentals - EF series MECHANISMS Cam, Crank and Toggle – EF-3.1 EF SERIES

The Engineering Fundamentals range enables students to gain an AN INNOVATIVE HANDS ON MODULAR SYSTEM DESIGNED TO ENABLE understanding of the principles of engineering by the process of learning INVESTIGATION AND THE UNDERSTANDING OF ENGINEERING PRINCIPLES via experimentation. The EF-3.1- Cam, Crank and Toggle experiments kit provides students with an introduction to cams and rollers and additionally crank motion and toggle. The kit is designed to help students understand how cams are used, to show how the rotational motion of a cam is transmitted to the linear motion of a follower and how different shapes of cam can be used to achieve varying magnitude and duration of linear motion. Similar to cams, a crank mechanism can transform rotational motion into linear motion although unlike cams, cranks can also work in the opposite direction, transferring linear motion into rotational motion.
