Torque

Torque, also known as moment of force or torsional moment, is a physical quantity that describes the tendency of a force to produce rotation or twisting of an object about an axis. It is basically a force acting at a certain distance from the axis of rotation. Torque is an important concept in mechanical physics and has a significant effect on the motion of rotating bodies and mechanical systems.

Definition of torque: Torque (τ) is a vector quantity that is calculated as the product of the force (F) acting perpendicular to the arm (r), which is distant from the axis of rotation: τ=F⋅rτ=F⋅r

The unit of torque in the International System of Units (SI) is the newton meter (N·m). This unit corresponds to a force of one newton applied to an arm of one meter length, which produces a torque of one newton meter.

Examples of using torque:

When opening or closing the door, a torque is created on the handle.
When a screwdriver is used to tighten a screw, torque is created on the screwdriver head.
Engines and machines use torque to create rotary motion.
If the external torques on the object are balanced by the internal torques, the object can be in an equilibrium state of rotation.
