Moment of Inertia of Human body

  1. Jul 19, 2006 #1
    I am having a lot of trouble trying to find the moment of inertia of myself, a male 5'10", and 165lbs. It seems as if it should be simple but am unsure how to take this one on. Any help would be great thanks.

    Hello thatsamazing10 :cool:

    The moment of inertia will certainly depened on the posture (does the person spread his legs/arms?). I'm not sure about the mass distribution in a human body and haven't found a scheme for usual limb masses yet. Maybe the biologists in this forum can help you out with that? :smile:

    But for an easy start you might assume an even mass distribution along a cylinder before trying to model more difficult postures.

    Regards,

    It's not really a cylinder..... I would say it's more of a rectangular prism

    Just had a look in the mirror :uhh: ... and ... you are right! I do look like a prism! :surprised :redface:

    Now, calculating a lollipop-shape would be cool! :cool:
