pöörlemisvõimas

Pöörlemisvõimas is an Estonian term that can be translated as rotational power or torque. It refers to the measure of the twisting force that causes an object to rotate around an axis. In physics, torque is a vector quantity, meaning it has both magnitude and direction. The magnitude of torque is determined by the force applied and the distance from the axis of rotation to the point where the force is applied.

The concept of pöörlemisvõimas is fundamental in understanding rotational motion, similar to how force is crucial for linear motion. It is responsible for changes in an object's angular velocity. For instance, when an engine generates pöörlemisvõimas, it can cause a car's wheels to spin. Similarly, a wrench applied to a bolt creates pöörlemisvõimas to tighten or loosen it.

The unit of pöörlemisvõimas in the International System of Units (SI) is the newton-meter (N⋅m). In other contexts, units like foot-pound (ft⋅lb) are also used. The direction of pöörlemisvõimas is typically defined by the right-hand rule, indicating the axis of rotation. Understanding pöörlemisvõimas is essential in fields such as mechanical engineering, where it is used to design and analyze machinery, engines, and various mechanical systems. It quantifies the effectiveness of a force in producing rotation.
