I've got an aluminum rectangular mass with two steel pins that I need to rotate at a high speed. It is 26" x 4.5". The aluminum weighs 46lbs, and the pins are 8.5lbs each. The pins are centered 11.25" left and right off center. I need to spin it 90 degrees in .450 sec (start and stop), via a 1 7/16" shaft mounted below in center. I'm having trouble calculating the moment of inertia and the forces/torque required to preform that operation. Any help would be appreciated.
