The circular disk of 200-mm radius has a mass of 25 kg with centroidal radius of gyration mm and has a concentric circular groove radius cut into it. A steady force T is applied at an angle θ to a cord wrapped around the groove as shown. If determine the angular acceleration α of the disk, the acceleration a of its mass center G, and the friction force F which the surface exerts on the disk.
