EF-3.1 – Mechanisms – Cam, Crank and Toggle

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.

Description

The Engineering Fundamentals range enables students to gain an understanding of the principles of engineering by the process of learning 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.

 Engineering fundamentals system

The modular tray-based system is supplied in conjunction with a multifunctional work panel enabling the student to conduct their own experiments in subjects such as statics, dynamics, mechanisms and kinematics.

Each kit is supplied with a highly visual user-friendly operational guide, allowing the student to understand the theory of the subject by the application of practical experimentation.
