    Moment of inertia for a hollow cube. Rotating about diagonal opp corners

    Certianly it'll be within a sealed enclosure. Ok that makes sense that it is still through the cofg but ... its dimensions.. the space it revolves through are different than if the axis passed through the centre of two oppsed walls... so its moment of inertia is still the same or different...

    Moment of inertia for a hollow cube. Rotating about diagonal opp corners

    Your right - I have no idea what your talking about..:-p It will experience acceleration - depending on the motor drive I can fit to it. From stationary up to 360 RPM. The acceleration will be dependant on the power of the motors but does not have to be rapid.

    Moment of inertia for a hollow cube. Rotating about diagonal opp corners

    Hi Folks, I am designing a piece of kinetic scultpure that will involve cubes made from aluminium square tubing rotating around an axis that passes through two diagonal corners. I am trying to determine motor size to drive this thing, and to do that I need to know its moment of inertia. Math...
