Key Terminology
-
Kilogram square millimeter
-
A derived moment of inertia unit equal to mass multiplied by the square of distance, representing resistance to angular acceleration in metric units.
-
Pound-force inch sq. second
-
A moment of inertia unit in the English engineering system expressed as pound-force times inch times second squared.
-
Moment of inertia
-
A measure of an object's resistance to angular acceleration based on mass distribution relative to an axis.
