Moments of inertia MOI are fundamental mass properties that provide information on a vehicles mass distribution. The properties impact vehicle design and safety and are primary inputs to vehicle dynamics and mobility computer models, where MOI data for a vehicles total, sprung, and unsprung masses are often required. Moments of inertia are also useful in the design and construction of vehicle safety outriggers needed during the conduct of dynamic handling tests. This document describes practical methods for the determination of the mass MOI of large, heavy military vehicles, typically about the centroidal axes.
