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 τ {\displaystyle {\boldsymbol {\tau }}} , the lowercase Greek letter tau .
The cross product \(\vec{r} \times \vec{F}\) also tells us the sign of the torque. In Figure \(\PageIndex{2}\), the cross product \(\vec{r} \times \vec{F}\) is along the positive z-axis, which by convention is a positive torque.

18 paź 2024 · Torque represents the force that causes an object to rotate about an axis. Just as force causes an object to accelerate in a straight line, torque makes the object rotate about an axis with angular acceleration. Torque is a vector quantity whose direction depends on the force.
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 the rotational counterpart of force. Suppose a body rotates about an axis and a force \(F\) is applied some distance \(r\) from the axis (Fig. \(\PageIndex{1}\)). The distance from the rotation axis to the point at which the force is applied is called the moment arm.
26 maj 2024 · Understanding Torque in Classical Mechanics. Torque, a fundamental concept in classical mechanics, plays a pivotal role in explaining how forces cause rotational motion. Also known as the moment of force, torque provides a deeper understanding of the principles behind the turning effect of forces on objects. Principles of Torque.
