What is a parallel axis theorem?
How can the parallel axis theorem determine the moment of inertia?
How to find centroidal moment of inertia using parallel axis theorem?
Use the parallel axis theorem to find the moment of inertia of the circular ring about the \(y\) axis. The dimensions of the ring are \(R_i = \mm{30}\text{,}\) \(R_o = \mm{45}\text{,}\) and \(a = \mm{80}.\)
The parallel axis theorem states that if the body is made to rotate instead about a new axis z′, which is parallel to the first axis and displaced from it by a distance d, then the moment of inertia I with respect to the new axis is related to Icm by. Explicitly, d is the perpendicular distance between the axes z and z′ .
The parallel axis theorem is the method to find the moment of inertia of the object about any axis parallel to the axis passing through the centroid. This theorem is applicable for the mass moment of inertia and also for the area moment of inertia.

Jul 28, 2023 · The parallel axis theorem gives a relationship between the moment of inertia of a rigid body about an arbitrary axis and the moment of inertia about an axis passing through the center of mass and parallel to the former.
Apply the parallel axis theorem to find the moment of inertia about any axis parallel to one already known; Calculate the moment of inertia for compound objects
The Parallel Axis Theorem. The moments of inertia about an axis parallel to an axis going through the center of mass is: I = I C M + m d 2. 🔗. where d is the perpendicular distance between the axes. 🔗.
