The problem statement A stiff uniform wire of mass M0 and length L0 is cut, bent, and the parts soldered together so that it forms a circular wheel having four identical spokes coming out from the center. None of the wire is wasted, and you can neglect the mass of the solder. What is the moment of inertia of this wheel about an axle through its center perpendicular to the plane of the wheel? 2. Relevant equations I (from end of rod) = mL^2/3 3. The attempt at a solution Itotal = 4 * ((M0/4)(L0/4)^2)/3 = M0L0^2/48 -- What am I doing wrong?
