A Newton Meter (N·m) is a unit of measurement used to quantify torque, which is the rotational force applied to an object. It is defined as the torque resulting from a force of one Newton applied perpendicularly to a lever arm that is one meter long. This unit is commonly used in engineering and physics to describe the effectiveness of a force in causing rotation. In practical applications, the Newton Meter is often used in various fields, including automotive engineering and machinery, to specify the torque specifications for bolts and other components. Understanding torque is essential for ensuring proper assembly and operation of mechanical systems, making the Newton Meter a vital measurement in these industries.
