Unformatted text preview: r 3 a 2 + = 2 0.0906 rad s = Problem 19-42 Disk A has a weight W A . An inextensible cable is attached to the weight W and wrapped around the disk.The weight is dropped distance h before the slack is taken up. If the impact is perfectly elastic, i.e., e = 1, determine the angular velocity of the disk just after impact. Given: W A 20 lb = h 2 ft = W 10 lb = r 0.5 ft = Solution: v 1 2 gh = Guess 2 1 rad s = v 2 1 ft s = 656...
