Centrifugal force (TM 600)

laws of the behaviour of rotating masses



  • Centrifugal force occurs in the motion of a rigid body on an orbit and is the inertia force, which acts with a direction away from the centre of rotation.
  • The counter force associated with the inertial force is the centripetal force.
  • Both forces are of equal magnitude and opposite in direction.
  • Centrifugal forces occur in all rotating machinery such as turbines and must be controlled to prevent damage to machine elements.
  • The TM 600unit can be used to study centrifugal forces under various conditions.
  • The core of the experimental unit is a rotating arm on a vertical rotation axis.
  • Different masses are attached to the arm.
  • The orbital radius can be set via the position of the mass on the arm.
  • There are three different masses available.
  • The occurring centrifugal force is transferred from the arm to a bending beam.
  • The force-proportional deformation is detected via an electronic measuring system and displayed digitally.
  • The speed, also displayed digitally, of the controlled drive motor can be continuously adjusted.
  • A transparent protective cover above the rotating arm ensures safety: operation is only possible when the protective cover is properly attached.
