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.
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 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 ...
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.

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.
May 10, 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 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 ...
