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...

The parallel axis theorem is the theorem determines the moment of inertia of a rigid body about any given axis, given that moment of inertia about the parallel axis through the center of mass of an object and the perpendicular distance between the axes. The moment of inertia of any object can be determined dynamically with the Parallel Axis Theorem</i></b>.</p>.

I understand how the parallel axis theorem and product of inertia 'work,' but I don't understand what to do with this particular shape. It has the rounded corners, and I am given no information about them. I have area, Ix, Iy, etc given in a table, but that is all. Is there some way to go from Ix/Iy to Ixy or something?

en.wikipedia.org/wiki/Second_moment_of_area

The 2nd moment of area, also known as the area moment of inertia, or second area moment, is a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis.The second moment of area is typically denoted with either an for an axis that lies in the plane or with a for an axis perpendicular to the plane.

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.
