The torque is then related to the lever length, shaft diameter and measured force. By using this site, you agree to the Terms of Use and Privacy Policy.

A friction band is wrapped around half the drum’s circumference and each end attached to a separate spring balance. To add new comment, please Login. The term ” brake horsepower ” fteno one measurement of power derived from this method of measuring torque. Use the field below to search for the desired community maker.

If the engine speed is measured with a tachometerthe brake horsepower is easily calculated. In its simplest form an engine is connected to a rotating drum by means of an output shaft.

Prony brake

Lrony substantial pre-load is then applied to the ends of the band, so that each spring balance has an initial and identical reading. The friction is increased by tightening the belt until the frequency of rotation of the shaft is reduced.

In practice more engine power can then be applied until the limit of the engine is reached. Retrieved from ” https: Thanks for Joining the CircuitMaker Community! There are no requests to display.

The Prony Brake is a simple device invented by Gaspard de Prony to pronyy the torque produced by an engine. This page was last edited on 23 Octoberat Essentially the measurement is made by wrapping a cord or belt around the output shaft of the engine and measuring the force transferred to the belt through friction.

The device is generally used over a range of engine speeds to obtain power and torque curves for the engine, since there is a non-linear relationship between pronny and engine speed for most engine types. Are you sure you want to delete this Release?

Views Read Edit View history. When the engine is running, the frictional force between the drum and the band will increase the force reading on one balance and decrease it on the other.
