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 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.
Dec 30, 2017 · Torque is the Moment of Force (Rotational domain equivalent of Force). It is the determining factor of how effectively a force can twist or turn something. This post is all about the torque formula sets, their step by step derivation and calculation of torque using formula while solving a numerical problem.

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.
Torque has both magnitude and direction. (a) A counterclockwise torque is produced by a force →F acting at a distance r from the hinges (the pivot point). (b) A smaller counterclockwise torque is produced when a smaller force →F′ acts at the same distance r from the hinges.
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.
The symbol for torque is this fancy T. It's the Greek letter tau. And the amount of torque caused by a force, so you need a force to cause a torque, but it's more than just force. You have to multiply r, the distance from the access to the force by the amount of force in order to find how much torque is being exerted by a given force.
