torque Turning effect of a force. A turbine produces a torque on its rotating shaft to turn a generator. The output of a rotary engine, such as the familiar four-stroke engine or an electric motor, is rated by the torque it can develop. A measurement is made by multiplying the force by its perpendicular distance from the turning point. The unit of measurement is the newton metre (Nm).
