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 ... Mass moment of inertia, or inertia as it will be referred to from here on, is resistance to rotation. The bigger the inertia, the slower the rotation. ∑M=Iα∑M=Iα. Inertia is always positive and has units of kgm2 or slugft2. For an infinitesimal unit of mass, the inertia depends on how far it is from the axis of rotation. … See more Specific inertia equations depending on the shape of the object and axis of rotation can be found below.
