Unformatted text preview: = v A 14.2 ft s = *Problem 18-40 The system consists of disk A of weight W A , slender rod BC of weight W BC , and smooth collar C of weight W C . If the disk rolls without slipping, determine the velocity of the collar at the instant the rod becomes horizontal, i.e. = 0 . The system is released from rest when = . Solve using the conservation of energy. Given: W A 20 lb = L 3 ft = W BC 4 lb = r 0.8 ft = 617...
