The circular disk of 270-mm radius has a mass of 36 kg with centroidal radius of gyration k⎯⎯k¯ = 235 mm and has a concentric circular groove of 105-mm radius cut into it. A steady force T is applied at an angle θ to a cord wrapped around the groove as shown. If T = 59 N, θ = 29°, μs = 0.08, and μk = 0.07, 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. The angular acceleration α is positive if counterclockwise, negative if clockwise; the acceleration a is positive if to the right, negative if to the left; and the friction force F is positive if to the right, negative if to the left..
A turntable is used to test an intentionally weak adhesive by coating the bottom of a 0.3 kg block with the adhesive and pressing it firmly to the turntable 0.4 meters from its center. The turntable starts from rest at t=0 and uniformly accelerates with an angular acceleration of a= 4.5 rad/s^2. If the adhesive fails exactly 2 seconds after the turntable starts rotating determine: (a) The angular displacement of the turntable at the time of failure. (b) The number of revolutions the turntable has made at the time of failure. (c) The total shear force which the adhesive supports given this failure.
