"N m" stands for "Newton meter," which is a unit of torque in the International System of Units (SI). Torque is a measure of the rotational force applied to an object, such as turning a bolt or rotating a wheel. One Newton meter is defined as the torque resulting from a force of one Newton applied perpendicularly at a distance of one meter from the pivot point. In practical terms, N m is commonly used in engineering and physics to describe the effectiveness of engines, motors, and other mechanical systems. Understanding torque in N m helps engineers design machines that operate efficiently and safely, ensuring they can handle the required loads and forces during operation.
