Right-angle lever paradox - Am. J. Phys.

    "Right-angle lever paradox" - Am. J. Phys.

    I'd like to read this article

    "Right-angle lever paradox," J. Charles Nickerson and Robert T.
    McAdory, Am. J. Phys. 43, 615 (1975)

    ----------------------------------------------------
    Abstract: We present the problem of relativistic torques with particular reference to the right-angle lever problem and outline a simple solution. The important elements of our solution are, first, a reexamination of the classical relation between torque and angular momentum and, second, the consequent realization that in relativistic analysis there exists a net internal torque which exactly cancels the net external torque experienced by an extended body in dynamic equilibrium. We find that the lever has constant angular momentum according to all Lorentz inertial reference systems and that this is consistent with the relativistic relationship between torque and angular momentum. Our solution is not restricted to relativity. It is valid for a wider class of theoretical frameworks.

    But I don't have ready access to a library. Does anyone have this article? If so then can you e-mail a scanned copy to me? Thanks

    pmb,

    You don't live near a university library?

    No. The nearest one is 35 miles away. And I'm still at a point where I get fatigued exstremely easy. I can get there but it will take a month or so and will be an all day event.

    Well, I have electronic access to Am. J. Phys., but unfortunately they electronic archive only goes back to 1975. The next time I'm at Stanford, I'll scan it for you -- but it may be a week or more. Maybe someone else can do it more easily?

    Dude!! You have access to Am. J. Phys.?? Awesome! There are two other articles I'd love to have.

    Apparatus to measure relativistic mass increase, John W. Luetzelschwab, Am. J. Phys. 71, 878 (2003)

    Faster-than-light speeds, tachyons, and the possibility of tachyonic neutrinos, Robert Ehrlich, Am. J. Phys. Vol. 71(11) pp. 1109-1114

    Each looks very interesting. Especially since they are the topic of my research.

    Can you e-mail them to me? If so it would be much appreciated.

    pmb,

    I'll snag 'em for you when I get home. Unfortunately, my work does not allow me to access my university's proxy server, which I need to get into Am. J. Phys!
