The two uniform thin discs shown in the figure rest on a horizontal plane and are connected through frictionless pin-joints at A and B by a rigid light rod which remains horizontal. The mass of disc A is 15 kg. and that of disc B is 25 kg. The static coefficients of friction between the plane and discs A and B are, respectively, (u)= 0.2 and (u)=0.55. At the instant shown, a counterclockwise moment T = 125 Nm is applied to disc B. You are required to,
