WebThe moment of inertia (MOI) is one of the many mass properties that describe an object’s stability and the forces needed to alter its motion. For aerospace engineering, stability is a crucial element in designing and manufacturing air and spacecraft. Knowing the MOI about various axes is vital to determining how a device can hold up to ... WebThe mass moment of inertia, usually denoted I, measures the extent to which an object resists rotational acceleration about an axis, and is the rotational analogue to mass. Mass moments of inertia have units of dimension mass x length^2. It should not be confused with the second moment of area, which is used in bending calculations.
