In physics and mechanics, torque is the rotational analogue of linear force. [ 1] 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.
Mar 28, 2023 · The basic formula for torque is =, where torque is represented by the Greek letter tau (τ) and equals the force (F) times the distance (or radius, r). If you know the magnitude of the force (in Newtons) and the distance (in meters), you can solve for the torque, expressed in newton-meters (N∙m). [4]

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.
Sep 12, 2022 · Describe how the magnitude of a torque depends on the magnitude of the lever arm and the angle the force vector makes with the lever arm. Determine the sign (positive or negative) of a torque using the right-hand rule. Calculate individual torques about a common axis and sum them to find the net torque.
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. The ...

The last equality in the above equation comes from definition of Newtons: F = ma = [kg ⋅ m/s2] ≡ [N]. So we find that torque will have units of force times length. Let's examine a simple example of a point mass attached to a massless rod of length r as shown in Figure 7.5.1.
Apr 6, 2023 · Torque Formula Torque is the product of force and distance of the point of application of force and the axis of rotation. \[ Torque (\tau ) = Distance (d) \times Force (F) \\ => \tau = rF \]
The torque of a force around a point is basically a measure of how effective the force would be at causing a rotation around that point. Since \(|\vec{r} \times \vec{F}|=r F \sin \theta\), you can see that it depends on three things: the magnitude of the force, the distance from the center of rotation to the point where the force is applied ...
