Moment of Inertia Calculation

  1. Nov 2, 2007 #1
    So i have a uniform density rod of mass M and length L. Now i want to bend it into a square shape with side length "a" where a is equal to "4/L". The thing is i only know how to calculate moment of inertia for objects with constant radii. does anybody have any recommendations to help me along?

    I think you mean a is equal to L/4. Where is the axis of rotation? The center of the square?
