    Rotated Section - Moment of Inertia

    Ok, i will explain a little bit: 1. You have a 2D Area in a XY axis. You can calculate the Moments of Inertia Ix, Iy, Pxy. 2. You rotate the 2D Area around the origin, with a tetha angle. 3. So, known Ix, Iy, Pxy and tetha: Is there a formula so i can calculate the new Ix, Iy, Pxy around the...

    Rotated Section - Moment of Inertia

    Hi everybody: I can see that there are formulas to calculate the moment of inertia of a 2D Area (Second moment of area) here: http://en.wikipedia.org/wiki/Second_moment_of_area In the same link, there is a formula to calculate the Inertia moments about a ROTATED AXIS (Axis Rotation). But, is...
