WebMoment of Inertia is also known as the angular mass or rotational inertia. The SI unit of moment of inertia is kg m 2. Moment of inertia is usually specified with respect to a chosen axis of rotation. It mainly depends on the distribution of mass around an axis of rotation. MOI varies depending on the axis that is chosen. Table of Content. Formula
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 ... WebA moment of inertia of a hollow sphere will be the same as any axis passing through its center. Ix = Iy = Iz = I. Let’s assume a dm mass on the shell; we will calculate the moment of inertia of this dm mass and then integrate it later to obtain the moment of inertia for the complete sphere. We know A = 4R².
