prony brake การใช้
ประโยค
- The "'Prony Brake "'is a simple device invented by Gaspard de Prony to measure the torque produced by an engine.
- Horsepower was originally measured and calculated by use of the " indicator diagram " ( a James Watt invention of the late 18th century ), and later by means of a Prony brake connected to the engine's output shaft . More recently, an electrical brake dynamometer is used instead of a Prony brake.
