A bar of mass m = 5 kg is held as shown between four disks each of mass m’ = 2 kg and radius r = 75 mm. Knowing that the forces exerted on the disks are sufficient to prevent slipping and that the bar is released from rest, for each of the cases shown, determine the velocity of the bar after it has moved through the distance h.
End A of the 8-kg uniform rod AB is attached to a collar that can slide without friction on a vertical rod. End B of the rod is attached to a ver- tical cable BC. If the rod is released from rest in the position shown, determine immediately after release (a) the angular acceleration of the rod, (b) the reaction at A.
Please show clear diagrams.
2. Two 20-kg uniform bars are connected to form the linkage shown. Neglecting the effect of friction,
determine the reaction at D immediately after the linkage is released from rest in the position shown.
