10.66: The accelerations of blocks A and B will have the same magnitude a . Since the cord does not slip, the angular acceleration of the pulley will be . R a = α Denoting the tensions in the cord as , and B A T T the equations of motion are , 2 a R I T T a m g m T a m T g m B A B B B A A A = - = - = - where the last equation is obtained by dividing α τ I = by R and substituting for α in terms of a . Adding the three equations eliminates both tensions, with the result that
