Rotational inertia is the force which prevents the movement of a                rolling or spinning object.  Research to be conducted uses                      electrorheological (ER) fluids along with computerized control                  systems to alter the rotational inertia of a wheel.  By doing so                the wheel and its load (an automobile, for example) can instantly               change its speed by electrically altering the rotational inertia                of the wheel.                                                                                                                                                   The objectives of this investigation are:  (1) control the                      rotational inertia of a wheel by controlling a fluid inside the                 wheel using valves which are electrically operated by electro-                  rheological fluids, and (2) quantify the efficiency in terms of                 energy use and speed of a computer control version to estimate                  its range of real world applications.  Controlling the direction                of the fluid throughout the wheel would entail an extensive                     system of valves and hydraulics.  In this experiment, ER fluid                  valves will be positioned throughout the interior cavity of the                 wheel.  In this manner a microprocessor-based digital/analog                    control system can electrically operate the ER valves.
