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.
τ = F ⋅ r . The direction of the torque vector is found by convention using the right hand grip rule. If a hand is curled around the axis of rotation with the fingers pointing in the direction of the force, then the torque vector points in the direction of the thumb as shown in Figure 2.
Torque Formula. T = F × r × sinθ. T = torque. F = linear force. r = distance measured from the axis of rotation to where the application of linear force takes place. theta = the angle between F and r. In this formula, sin(theta) has no units, r has units of meters (m), and F happens to have units of Newtons (N).
The equation for the magnitude of a torque, arising from a perpendicular force: τ = ( distance to centre ) ( force ) . {\displaystyle \tau =({\text{distance to centre}})({\text{force}}).}
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. \[ Torque (\tau ) = Distance (d) \times Force (F) \\ => \tau = rF \]

Sep 12, 2022 · 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.
Nov 8, 2022 · The equation above only give the magnitude of the torque, while the right-hand rule determines the direction. Mathematically, a cross product contains both the magnitude and direction of torque: \[\vec\tau=\vec r\times\vec F\]
Nov 25, 2023 · The equation for torque is derived from the Angular Momentum Principle, which states that torque is equal to the change in length over time. Another equation used to represent torque is [math]\displaystyle{ {\Delta}{\vec{L}} = {\vec{\tau}} \times {\Delta}t }[/math]
In this section, we define torque and make an argument for the equation for calculating torque for a rigid body with fixed-axis rotation. Defining Torque So far we have defined many variables that are rotational equivalents to their translational counterparts.
