Forgatónyomatékra

Forgatónyomatékra is a Hungarian term that translates to "torque" in English. It is a measure of the rotational force applied to an object. In physics, torque is the equivalent of linear force for rotational motion. Just as a linear force causes an object to accelerate linearly, a torque causes an object to accelerate rotationally.

The magnitude of torque is calculated by multiplying the force applied by the perpendicular distance from the pivot point to the line of action of the force. This distance is often referred to as the lever arm. The formula for torque is typically represented as $\tau = r \times F$, where $\tau$ is the torque, $r$ is the lever arm vector, and $F$ is the force vector. The direction of the torque is determined by the right-hand rule, indicating the axis of rotation.

Torque is a vector quantity, meaning it has both magnitude and direction. Its SI unit is the newton-meter (N·m). Common examples of torque include the force applied to a wrench to turn a bolt, the rotational force exerted by an engine on a crankshaft, or the torque produced by a person pedaling a bicycle. Understanding torque is crucial in various fields, including mechanical engineering, physics, and astronomy, where it plays a role in the motion of celestial bodies and the design of machinery.
