A dynamometer is a device used to measure force, torque, or power in various mechanical systems. It is commonly employed in automotive testing to evaluate engine performance, ensuring that vehicles meet specific standards. By providing accurate measurements, dynamometers help engineers and manufacturers improve designs and efficiency. There are different types of dynamometers, including mechanical and electronic versions. Mechanical dynamometers often use springs or levers, while electronic ones utilize sensors and digital displays for precise readings. These tools are essential in industries such as automotive, aerospace, and manufacturing for optimizing performance and safety.
