A massless spool of inner radius r outer radius R is placed against a vertical wall and a tilted split floor as shown A light inextensible thread is tightly wound around the spool through which a mass m is hanging There exists no friction at point A while the coefficient of friction between the spool and point B is The angle between the two surfaces is p g R r C A B
