The wheels of a wagon can be approximated as the combination of a thin outer hoop of radius rh = 0.315 m and mass 4.89 kg, and two thin crossed rods of mass 7.37 kg each. Imagine replacing the wagon wheels with uniform disks that are ta = 5.88 cm thick, made out of a material with a density of 6450 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 of the disk be? ta rd = 0.169 Incorrect m
