Area Moment of inertia of a circular wire

  1. Mar 5, 2010 #1
    Hlw.....I am a new guy here.....And I am taking a course of Applied Mechanics in my freshmen year....Here I have come across a term called Area of moment of inertia which I don't really understand that much........And I have been given to prove that
    [tex]
    I_d = \frac{\pi a^4}{4}
    [/tex]......I was trying everything but I am at my wit's end.......So, if some helps me it would be great.......A thanks in advance for the help....

    Welcome to PF!

    Hi i_m_sadiq! Welcome to PF! :smile:

    Area (no "of" :wink:) moment of inertia is another name for second moment of area.

    Search google or wikipedia for "second moment of area" and/or see the PF Library on moment of area :smile:
