For the scalar form, the Huygens-Steiner theorem allows for it to be calculated for a rigid object with a displaced axis of rotation, and is also known as the parallel axis theorem.
In its tensor form, this can be defined through a 3x3 matrix where its elements off of the principle diagonal are called "products". By putting the tensor into reduced row-echelon form, the principal type of this can be determined from the values of the principle diagonal. For the scalar form, the Huygens-Steiner theorem allows for it to be calculated for a rigid object with a displaced axis of rotation, and is also known as the parallel axis theorem. For 10 points, name this principle that was first defined by Euler in 1730, the rotational analog of mass.
