Fundamentals of mechanical friction (TM200)

Fundamentals of mechanical friction (TM200)

stationary friction body, uniformly moving friction plate

CodeTM200

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.
