Is this body rotating? Will line AB always be
If the cord CF is suddenly cut what will the angular
velocity of cord AD and BE be immediately after the
cut is made? What does that say about the acceleration
of points A & B (Think about the ?? x R and -?2R
Remember that the vectors on the FBD and the
kinetic diagram represent equivalent vector systems
thus, ?MA on the FBD must equal ?MA on the kinetic
diagram where A can be any point.
