Bifilar pendulum motion

  1. Jun 14, 2012 #1
    Heyy guys,

    I have and EEI to do on a bifilar pendulum. Essentially a bifilar pendulum is acheived by two parallel strings instead of one. I have already built the device but dont know how the motion should be. Shourd it be farwards adn backwars? or side to side? or rotate?

    Thanks in advance:)

    welcome to pf!

    heyy joelKID984! welcome to pf! :smile:

    "bifilar" simply means "having two threads", so it could be used in any of those three ways

    but i believe it's usually operated as a torsional pendulum …

    for pictures, do a google image-search for "bifilar pendulum" :wink:

    how does a bifilar pendulum relate to the world

    ok,

    im doing an EEI on a bifilar pendulum and im on one of the lest sections of the report that quite important as it shows critical thinking. i have to discuss how the bifilar pendulum relates to the real world.

    essentially a bifilar pndulum if a pendulum with two parallel filaments attached to a body instead of one. i know that a bifilar pendulum is used to measure moment of inertia, but how can it relate to the real world.

    Thanks,
    Joel
