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.
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.
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 16, 2024 · Torque is also called the “moment of force,” as it depends on the magnitude of the force as well as the moment of the arm, i.e., the perpendicular distance between the line of action force and the axis of rotation. Torque is as fundamental to rotational motion as force is to a straight-line motion.
Apr 6, 2023 · Because it is a product of some distance and a physical entity like force, torque is also called moment of force. r is called the length of the moment arm or lever arm. Also, since the rotating object describes a circle, r is the radius. Notice that the longer the lever arm, the higher the torque.
Jun 20, 2024 · torque, in physics, the tendency of a force to rotate the body to which it is applied. 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.
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.
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 8, 2022 · The right mass causes a torque into the page, while the left mass generates a torque out of the page. To balance torque, in addition to the direction being opposite, their magnitudes need to be the equal, \(\tau_1=\tau_2\).
