Definition of Dynamometer: A dynamometer is a device used for measuring force, torque, or power. In automotive applications, it’s commonly used to measure the power output of an engine, motor, or other rotating prime movers. There are various types of dynamometers, including engine dynamometers, chassis dynamometers, and hand-held dynamometers, each serving different measurement purposes. These instruments are essential in fields like mechanical engineering, rehabilitation, and exercise physiology for evaluating performance and strength.
Etymology and Origin: The term ‘dynamometer’ combines the Greek words ‘dynamis‘, meaning ‘power’ or ‘force’, and ‘metron‘, meaning ‘measure’. Its use dates back to the 19th century, coinciding with the development of machinery and engines where measuring power output became crucial. The dynamometer has evolved over time, with advancements in technology leading to more precise and diverse applications of the device.
