Perhaps you should try some spelling variations:
rotational inertia » rotational energy, rotational kinematics, rotational invariant
rotatory inertia » rotary inertia
rotor inertia » rotary inertia, monitor inertia, motion inertia

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rotor inertia) OR (rotatory inertia))) OR (rotational inertia)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rotor inertia) OR (rotatory inertia))) or (rotational inertia))".
• Adding a wildcard symbol may retrieve word variants: ((((rotor inertia) OR (rotatory inertia))) or (rotational inertia))*.
