Friction torque

Friction torque

Friction torque is the torque caused by the frictional force that occurs when two objects in contact move. Like all torques, it is a rotational force which may be measured newton metres or pounds-feet.

Engineering

Friction torque can be disruptive in engineering. There are a variety of measures engineers may choose to take to eliminate these disruptions. Ball bearings are an example of an attempt to minimize the friction torque.

Examples

*When a cyclist applies the brake to his/her forward wheel, the bike tips forwards due to the frictional torque between the wheel and the ground.

*When a golf ball hits the ground it begins to spin in part because of the friction torque applied to the golf ball from the friction between the golf ball and the ground.
