Homework Statement
The thin, homogeneous bent rod has the mass m and the total length of 4b. It rotates with the angular speed of ω = ω0(24i + 12j - 6.0k) (only rotation)
Determine the expression for the moment of inertia with consideration of the center of mass of the rod
The figure:

Homework Equations
H = (Ixxωx-Ixyωy-Ixzωz)i+(-Iyzωx+Iyyωy-Iyzωz)j+(-Izxωx-Izyωy+Izzωz)k
m = ρb
The Attempt at a Solution
¨I plotted the figure in yx-axis and could see that
Iyz=Iyx=Iyz=Izy=Ixz=Izx=0 is symmetric
But I'm not sure about Ixx, Iyy and Izz
