Q.9y A bar of mass m is held as shown between 4 disks, each of mass m' & radius r = 75 mm Determine the acceleration of the bar immediately after it has been released from rest, knowing that the normal forces exerted on the disks are sufficient to prevent any slipping and assuming that; (a) m = 5 kg and m' = 2 kg . (b) the mass m' of the disks is negligible. (c) the mass m of the bar is negligible.
