Friction brake


  • Webster's Revised Unabridged Dictionary
    • Friction brake (Mach) a form of dynamometer for measuring the power a motor exerts. A clamp around the revolving shaft or fly wheel of the motor resists the motion by its friction, the work thus absorbed being ascertained by observing the force required to keep the clamp from revolving with the shaft; a Prony brake.

In science:

This frictional braking acts on a time scale inversely proportional to the cluster mass and in triaxial galaxies it can be an order of magnitude shorter than in symmetric galaxies.
