Torque

In physics, torque can informally be thought of as "rotational force" or "angular force" which causes a change in rotational motion.

This force is defined by linear force multiplied by a radius.

The SI units for Torque are newton metres.

In the U.S., foot-pounds force are also commonly encountered.

The concept of torque, also called moment or couple, originated with the work of Archimedes on levers.

The rotational analogues of force, mass, and acceleration are torque, moment of inertia, and angular acceleration respectively.

The force applied to a lever, multiplied by its distance from the lever's fulcrum, is the torque.

For example, a force of three newtons applied two metres from the fulcrum exerts the same torque as one newton applied six metres from the fulcrum.

This assumes the force is in a direction at right angles to the straight lever..
