[QUOTE="Firben, post: 4752143, member: 360316"] [h2]Homework Statement [/h2] The thin, homogeneous bent rod has the mass m and the total length of 4b. It rotates with the angular speed of ω = ω[SUB]0[/SUB](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: [url]http://s716.photobucket.com/user/Pitoraq/media/Mek4_zps8205c021.png.html[/url] [h2]Homework Equations[/h2] H = (Ixxωx-Ixyωy-Ixzωz)i+(-Iyzωx+Iyyωy-Iyzωz)j+(-Izxωx-Izyωy+Izzωz)k m = ρb [h2]The Attempt at a Solution[/h2]¨ 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 [/QUOTE]
