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.
Torque is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an object to acquire angular acceleration. Torque is a vector quantity. The direction of the torque vector depends on the direction of the force on the axis.
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 τ {\displaystyle {\boldsymbol {\tau }}} , the lowercase Greek letter tau .
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.
Apr 6, 2023 · Torque is the product of force and distance of the point of application of force and the axis of rotation. T orque(τ) =Distance(d) ×F orce(F) => τ =rF T o r q u e ( τ) = D i s t a n c e ( d) × F o r c e ( F) => τ = r F.
We see the application of torque in many ways in our world. We all have an intuition about torque, as when we use a large wrench to unscrew a stubborn bolt. 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.
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. Get a grasp on the concept of net torque and its role in rotational motion. Created by Sal Khan.
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 ...
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, \(\tau_1=\tau_2\).
Nov 5, 2020 · The quantity \(\vec{r} \times \vec{F}\) is called the torque of a force around a point (the origin from which \(\vec r\) is calculated, typically a pivot point or center of rotation). It is denoted with the Greek letter \(\tau\), “tau”:
