The drum has a weight of 50 lb and a radius of gyration A 35-ft-long chain having a weight of 2 lb/ft is wrapped around the outer surface of the drum so that a chain length of s = 3 ft is suspended as shown. If the drum is originally at rest, determine its angular velocity after the end B has descended s = 13 ft. Neglect the thickness of the chain.
