Homework Help: Law of Length

  1. Nov 29, 2005 #1
    Can someone explain to me what Law of Length because I have tried to look for it in my textbook and the Internet but have been unsuccessful, so if someone can give me a link to finding what Law of Length is or tell me what it is, it would really help.

    "Law of Length"?? Never heard of it. Where did you hear the phrase?

    I just googled on "Law of Length" and now I know too much!

    Here is one possibility:
    http://www.pcmech.com/show/editorial/173/
    which says
    "Law III: Law of Length/Duration Elasticity
    Standardized lengths for things like cables can be extended by the sheer presence of a tech. Ex: in the presence of a tech, 18" IDE cables can reach lengths of at least 21", if not more. Also, routines with standard time lengths, like a boot, can be accelerated or delayed as necessary by the will of the tech. "

    Hmmm, I think that's a joke!

    Another:
    http://www.aapspharmaceutica.com/about/press/aapsexpertsdatabase/index.asp [Broken]
    which says:
    "Law of Length
    News reports are usually brief. Keep your responses short and to the point."
    Not sure whether that's a joke or not but not likely to be what you are looking for!

    I think it most likely what you are looking for is one of these:

    or
    http://www.msu.edu/user/sellmerr/measuring_time_accurately_and_na.htm
    which assert that the period of a pendulum is proportional to the square root of the length of the pendulum. Never thought of calling that a "law" myself!
