MEF Unité d'Étude de Friction

The Friction Study Unit, "MEF", allows the unit to illustrate the friction force by simple demonstrations.

It is designed for the study of the relations between friction forces and normal forces, between hard or soft surfaces, between lubricated or dry surfaces and between rolling surfaces for several types of materials.

The weight makes the roller set turn while another weight exerts some pressure on the brake. The relation between both of them determines the coefficient of friction for different materials and different operational conditions.
