Types of dynamometers: 1)Absorption dynamometer: Prony brake dynamometer Rope brake dynamometer Hydraulic dynamometer 2). Pony Brake is one of the simplest dynamometers for measuring power output ( brake power). It is to attempt to stop the. Prony Brake - Download as Powerpoint Presentation .ppt /.pptx), PDF File .pdf) applying a brake, Hence dynamometer is a brake with a device of measuring.


A Prony brake see figure develops mechanical friction on the periphery of a rotating pulley by means of brake blocks that are squeezed against the wheel by tightening the bolts until the friction torque FR balances the torque WL. The upper end of the rope is attached to a spring balance where as the lower end supports the weight of suspended mass.

It has two wooden blocks that are placed on a pulley which is fixed on the shaft of the engine whose power is to be measured. Eddy Current Dynamometer: The working principle of eddy current dynamometer is shown in the figure below. Absorption Dynamometers: Transmission dynamometers are also called torque meters.

This weight placed on the lever balances the brake when unloaded.
