This image displays an example situation where there is an active frictional torque. The large black vector arrow represents the primary force acting on the bar (the thick black line), causing it to rotate around the gray dot at its opposite end which represents an axle. The large red vector arrow represents the torque caused by the primary force. The small black vector arrow represents the frictional force caused by the bar sliding across the second bar (grey).
In mechanics, friction torque is the torque caused by the frictional force that occurs when two objects in contact move.[1] Like all torques, it is a rotational force that may be measured in newton meters or pounds-feet.
