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 = 6.25 kg. If the system is released from rest, determine the angular acceleration of the spool and the tension of the chain.

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
