The parallel axis theorem, also known as Huygens–Steiner theorem, or just as Steiner's theorem, named after Christiaan Huygens and Jakob Steiner, can be used to determine the mass moment of inertia or the second moment of area of a rigid body about any axis, given the body's moment of inertia about a parallel axis through the object's center of gravity and the perpendicular distance be...

It is a theorem that allows you to calculate the moment of inertia of a body through any axis of rotation provided that that 2 conditions are satisfied. The conditions are the following: 1. You need to have the moment of inertia of the body throug...

The parallel axis theorem is used in physics to determine an object’s moment of inertia as it rotates about any axis. The theorem states that there is a relationship between the inertia of an object rotating around its center of gravity and an axis parallel to this center. This theorem applies to any solid object in rotation, including irregular shapes.

What is the Parallel Axis Theorem? The parallel axis theorem can be used to determine the moment of inertia of a rigid body around any axis. Oftentimes the moment of intertia of a rigid body is not taken around the centroid, rather some arbitrary point. A good example of this is an I-Beam.

The application of parallel axis theorem for the rotation axis offset from the center of mass is depicted in the figure below. According to parallel axis theorem, moment of inertia is the sum of moment of inertia through mass center and product of mass and square of perpendicular distance between mass center and rotation axis.

parallel axis theorem mathematical method of relating the moment of inertia of a body or object around one axis to the moment of inertia of the same body or object around a parallel axis. Calculated as I 2 = I 1 + md 2 where I 1 and I 2 are the moments of inertia, m is the mass of the object and d is the distance between the two parallel axes.

Parallel Axis Theorem The moment of inertia of any object about an axis through its center of mass is the minimum moment of inertia for an axis in that direction in space. The moment of inertia about any axis parallel to that axis through the center of mass is given by

Parallel Axis Theorem Formula Questions: 1) A solid sphere with mass 60.0 kg and radius 0.150 m has a moment of inertia for rotation through its central axis. What will be the moment of inertia of the sphere, if the rotation axis is changed to pass through a point on its surface?

The Parallel Axis Theorem states that a bodies moment of inertia about any given axis is the moment of inertia about the centroid plus the mass of the body times the distance between the point and the centroid squared. This works for both mass and area moments of inertia as well as for both rectangular and polar moments of inertia. ...
