newtonméterben

The newtonméter (symbol Nm) is the SI derived unit of torque. Torque is a rotational or twisting force. It is defined as the product of a force and the perpendicular distance from the pivot point to the point where the force is applied. Therefore, one newtonméter is equal to the torque produced by a force of one newton acting at a perpendicular distance of one meter from the axis of rotation.

The newtonméter is not the same as a joule, which is the SI derived unit of energy or work. While both units are expressed in terms of newtons and meters, their physical meanings are different. Work or energy is a scalar quantity representing the transfer of energy, whereas torque is a vector quantity representing a moment or turning effect. In rotational motion, work done is the product of torque and angular displacement, with the latter being measured in radians.

The newtonméter is commonly used in engineering and physics to quantify twisting forces, such as those experienced by shafts, bolts, and engines. For instance, an engine's torque output is often specified in newtonméters. Similarly, when tightening a bolt, a torque wrench will measure and apply a specific torque value in newtonméters to ensure proper tightness without overtightening.
