Alarge bell is hung from a wooden beam so it can swing back andforth with negligible friction. the center of mass of the bell is0.60 m below the pivot, the bell has mass 34.0 kg, and the momentof inertia of the bell about an axis at the pivot is 18.0 kgm2 . the clapper is a small, 1.8-kg mass attached to oneend of a slender rod that has length l and negligible mass. theother end of the rod is attached to the inside of the bell so itcan swing freely about the same axis as the bell. what should bethe length l of the clapper rod for the bell to ring silently, thatis, for the period of oscillation for the bell to equal that forthe clapper?
