A weight of mass m is attached to the end of the string. The radius of the connecting tube is r and mass of the spool is M and radius is R. Find the acceleration of the falling mass m. Neglect the mass of the connecting tube and slipping of the spool.

A uniform rod of mass m and length l which can rotate freely in vertical plane without friction is hinged at its lower end on a tablev . A sphere of mass m and radius R = l/3 is placed in contact with the vertical rod annd a horizontal force F is applied at the upper end of the rod.
