EF-4.1 – Kinematics – Pulleys


EF-4.1 – Kinematics – Pulleys

The EF-4.1 – Pulleys experiments kit introduces students to various types of pulleys including fixed, movable and compound pulleys.


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

The EF-4.1 – Pulleys experiments kit introduces students to various types of pulleys including fixed, movable and compound pulleys. These experiments show the advantages of using different types pulleys as a way of lifting weights.

The kit also allows students to familiarise themselves with a simple windlass or wheel and axle and how this can allow a large load to be lifted whilst still maintaining a mechanical advantage, a differential windlass, how a capstan device allows high loads to be controlled by a relatively low restraining force and a Weston differential or chain hoist.

The kit introduces students to terms such as mechanical advantage, velocity ratio, work done, efficiency and the laws of a machine.

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.
