Weird I-beam with angles?

  1. Mar 22, 2012 #1

    So I'm trying to check the moment of inertia Ix for this weird I beam. The three steel plates' moments of inertia were easy enough to calculate. However, I would appreciate any help on how I should go about calculating the contribution of the four L6x6x1 angles to the total moment of inertia. Thanks.

    hi eurekameh! :smile:

    (btw, physicists call that moment of inertia the "second moment of area" :wink:)
    but isn't Ix given in the question? :confused:
