The wheels of a wagon can be approximated as the combination of a thin outer hoop of radius rh = 0.580 m and mass 5.65 kg, and two thin crossed rods of mass 7.80 kg each. Imagine replacing the wagon wheels with uniform disks that are ta = 4.62 cm thick, made out of a material with a density of 6910 kg/m³. If the new wheel is to have the same moment of inertia about its center as the old wheel about its center, what should the radius ra of the disk be? Ө rd = ۲۵ m
