pöörlemomendile

Pöörlemomendile, also known as torque, is a measure of the force that can cause an object to rotate about an axis. It is the product of the magnitude of the force applied and the perpendicular distance of the line of action of the force from the axis of rotation. The SI unit of torque is the newton metre (Nm).

Torque is a vector quantity, meaning it has both magnitude and direction. The direction of the torque is determined by the right-hand rule, where if the fingers of the right hand curl in the direction of rotation, the thumb points in the direction of the torque vector.

In mechanical systems, torque is crucial for understanding the behavior of rotating objects. For example, in an engine, torque is the rotational force that drives the vehicle's wheels. In electrical systems, torque is generated by the interaction between magnetic fields and current-carrying conductors, as seen in electric motors.

Torque can be either positive or negative, depending on the direction of rotation. Positive torque causes clockwise rotation, while negative torque causes counterclockwise rotation. The net torque on an object is the sum of all individual torques acting on it. If the net torque is zero, the object will not rotate.

In summary, pöörlemomendile, or torque, is a fundamental concept in physics and engineering, describing the rotational force acting on an object. It is calculated as the product of force and the perpendicular distance from the axis of rotation, and it plays a critical role in the analysis and design of various mechanical and electrical systems.
