Torque is the twisting force that tends to cause rotation. It is the measure of how much a force acting on an object causes that object to rotate. Visit to learn how to calculate torque along with its formula, meaning and applications.
In physics and mechanics, torque is the rotational analogue of linear force. It is also referred to as the moment of force (also abbreviated to moment). The symbol for torque is typically , the lowercase Greek letter tau. When being referred to as moment of force, it is commonly denoted by M.
Figure 1: Opening a door with maximum torque. Torque can be either static or dynamic. A static torque is one which does not produce an angular acceleration. Someone pushing on a closed door is applying a static torque to the door because the door is not rotating about its hinges, despite the force applied.
Apr 6, 2023 · A dynamic torque produces angular acceleration. For example, the drive shaft of a racing car produces angular acceleration allowing the race car to drive on its track. A wrench is activated by force applied at one end, creating an unbalanced torque on the tightened element.
Torque is at work in unseen ways, as when we press on the accelerator in a car, causing the engine to put additional torque on the drive train. Or every time we move our bodies from a standing position, we apply a torque to our limbs.
Jun 20, 2024 · The torque, specified with regard to the axis of rotation, is equal to the magnitude of the component of the force vector lying in the plane perpendicular to the axis, multiplied by the shortest distance between the axis and the direction of the force component.
The meaning of TORQUE is a force that produces or tends to produce rotation or torsion; also : a measure of the effectiveness of such a force that consists of the product of the force and the perpendicular distance from the line of action of the force to the axis of rotation.
Dec 28, 2020 · Torque is to rotational motion what force is to the world of linear motion, although it has units of newton-meters rather than newtons, and it is a vector cross product. The cross product of force and lever arm gives the torque, and its direction is found by using the right-hand rule.
An introduction to torque, a force that causes rotation. Understand how torque is calculated as the product of force and distance, and how it differs from work. Learn about the direction of torque and its units.
Nov 25, 2023 · Torque is the measure of how much a force acting on an object causes that object to rotate, creating a tendency for the object to rotate about an axis, fulcrum, or pivot. Torque is most commonly classified as "twist", rotational force, or angular force to an object and applying it to a system changes the angular momentum of the system.
