PROBLEM 9.115 The elliptical ring shown was cut from a thin, uniform plate. Denoting the mass of the ring by m , determine its moment of inertia with respect to ( a ) the centroidal axis , BB ( b ) the centroidal axis CC that is perpendicular to the plane of the ring. SOLUTION First note mass mV t A ρ = == ( )( ) 22 ta b a b ρπ 3 tab πρ = Also mass area I tI = area 3 m I ab π = ( a ) Using Figure 9.12,
