The 2-kg gear A rolls on the fixed plate gear C. Determine the angular velocity of rod OB about the z axis after it rotates one revolution about the z axis, starting from rest. The rod is acted upon by the constant moment M = 5 N • m. Neglect the mass of rod OB. Assume that gear A is a uniform disk having a radius of 100 mm.
