and the pulleys frictionless .There is no friction between block B and the support table B and C have masses m(A)= M and m(B) =m(C) = m. The strings are assumed maseless and unstreichable but there is friction between blocks B and C denoted by a given coefficient mu Given the setup shown in Fig Block A
