TM 200 Fundamentals of mechanical friction
The unit provides fundamental experiments on static and dynamic friction. Two solid bodies are moved against each other in a uniform manner. The frictional forces occurring in the process are measured. The friction body under investigation is connected to a force gauge and remains at rest.
The paired material is driven by a motor and slides beneath the friction body. Two sliding velocities can be selected. The normal force is altered by adding extra weight to the bodies.
All parts are clearly laid out and well protected in a storage system.
