The spool is pinned at its center at O, about which it can spin freely. The radius of the spool is R = 0.15 m, its radius of gyration is kO = 0.11 m, and the mass of the spool is ms = 5 kg. The mass B is suspended from the periphery of the spool by a chain of negligible mass that moves over the spool without slip. The mass of B is mB = 7 kg.

If the system is released from rest, determine the angular acceleration of the spool and the tension in the chain.
