quantitykind:Torque

Type
Description

In physics, a torque ($$\tau$$) is a vector that measures the tendency of a force to rotate an object about some axis. The magnitude of a torque is defined as force times its lever arm. Just as a force is a push or a pull, a torque can be thought of as a twist. The SI unit for torque is newton meters ($$N m$$). In U.S. customary units, it is measured in foot pounds (ft lbf) (also known as "pounds feet"). Mathematically, the torque on a particle (which has the position r in some reference frame) can be defined as the cross product: $$τ = r x F$$ where, r is the particle's position vector relative to the fulcrum F is the force acting on the particles, or, more generally, torque can be defined as the rate of change of angular momentum: $$τ = dL/dt$$ where, L is the angular momentum vector t stands for time.

Properties
$$L^2 \cdot M/T^2$$
$$kg \cdot m^2/s^2$$
$$\tau = M \cdot e_Q$$, where $$M$$ is the momentof force and $$e_Q$$ is a unit vector directed along a $$Q-axis$$ with respect to which the torque is considered.
