stationary friction body, uniformly moving friction plate

Description:

• 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.
