How Do You Calculate & Find Engine Torque?
Force is defined as a push or pull. Torque is a rotational force, because it makes objects turn or move in a circle. Engines operate using torque because they rotate shafts to perform activities such as turning wheels in cars. Torque depends on the engine speed, or how powerful an engine is. Power describes the rate at which work can be done by a force. The more powerful the engine, the greater the torque it will produce. RPM, or revolutions per minute, is used to describe circular motion. To calculate engine torque, it is necessary to use the relationship between it, horsepower and RPM. Torque is force multiplied by a distance. In British units, torque is measured in pound-feet, or lb-ft, and is usually denoted by the Greek letter tau. Power is equal to a force multiplied by the speed. In British units, horsepower is 550 ft-lb / s, or foot-lb per second or 33,000 ft* lb / min. RPM tells the time for an object such as the shaft of an engine to rotate when there is no load. Torque is eq
