Web25 apr. 2024 · When all the possible axes of rotation are taken into account, a tensor can be defined. Inertia tensor. For the same object, different axes of rotation will have different moments of inertia about those axes. In general, the moments of inertia are not equal unless the object is symmetric about all axes. The moment of inertia tensor is a ... sleeping above a stolen crownWebWith rotation matrices, I could align the inertia tensor that corresponds to the axis of maximum rotation symmetry with the z-axis, by rotating the molecule first around the x- axis to bring it in to the xz plane and then around the y- axis, to bring it at the same position as the z-axis of the cartesian coordinate system, and that works just fine. sleeping a lot symptomWeb23 jan. 2024 · Eigenvalues quantify inertia along principal axes, their ordering is irrelevant as long as the correspondance with eigenvectors is preserved.
