The wheels of a wagon can be approximated as the combination of a thin outer hoop of radius n= 0.156 m and mass 5.65 kg. and two thin crossed rods of mass 8.66 kg each. Imagine replacing the wagon wheels with uniform disks that are fa = 6.51 cm thick, made out of a material with a density of 7370 kg/m'. 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 of the disk be? m ra=
