Question

The circular disk of 145-mm radius has a mass of 38 kg with centroidal radius of gyration k bar = 25 mm and has a concentric circular groove of 55-mm radius cut into it. A steady force Tis applied at an angle theta to a cord wrapped around the groove as shown. If T = 40 N, theta = 0, mu_s = 0.11, and mu_k = 0.09, determine the angular acceleration a of the

The circular disk of 145-mm radius has a mass of 38 kg with centroidal radius of gyration k = 125 mm and has a
concentric circular groove of 55-mm radius cut into it. Ā steady force T is applied at an angle 0 to a cord wrapped around
the groove as shown. If T = 40 N, 0 = 0, µs = 0.11, and Hk = 0.09, determine the angular acceleration a 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
a 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.
