Question

Transcribed Image Text:The wheels of a wagon can be approximated as the combination of a thin outer hoop, of radius r, = 0.262 m and mass
5.08 kg, and two thin crossed rods of mass 7.37 kg each. A farmer would like to replace his wheels with uniform disks
ta = 0.0462 m thick, made out of a material with a density of 7830 kg per cubic meter. If the new wheel is to have the same
%3D
moment of inertia about its center as the old wheel about its center, what should the radius of the disk be?
ra =
