Thinking of writing a research paper on Gyroscopes

  1. Oct 28, 2009 #1
    Hi everyone

    Long time since i posted something.
    (May be i have posted at the wrong place, Doc Al...feel free to move it)

    I am in my first year... Basically i will have to start writing research papers from the next year... But i am really interested to start from the first year...

    I thought for a while and i think that "On the motion of precessing bodies" would be a good topic....I will cover nutation also....

    This is my first time i am writing a paper... and the obvious question "Where do i start from?"

    I have started going through various websites... I am thinking of some matlab simulation also...
    My reference material consists "Kleppner" and "Goldstein"(issued it just today)

    Help me friends...

    You might think about writing about applications of gyros, but not on the therory of the gyro itself. There is a closely related subject concerning the instability of solids spinning about their intermediate principal moment of inertia. This might be a more interesting subject. (Almost) Everbody already knows that "the polehode rolls on the herpolehode without slipping", but what happens when the solid is spinning about its intermediate principal moment of inertia? Could the Earth ever turn upside down?

    Yeah... Thats a goo advise... If i write anything about gyroscopes, it would be just some other usual educational paper... I want to write something original.... This thing looks good... I will think about...

    The Earth is a prolate spheroid, but a lot of the mass around the equator is water, so it can easily move to a new axis of rotation. How does the water conserve angular momentum if the Earth's axis of rotation changes?

    There is an article in Am. J of Phys, where the author discusses the precession with basic newtonian concepts as forces, particularly the centripetal force. He shows that prcession arises from the unbalancing of centripetal force from the various parts of the gyro. You should work more on this subject, may be a simulation. Sorry for not having the complete reference. I am moving and everything here is in boxes.

    Best wishes
