The mass center G of a 3-kg wheel of radius R=180 mm is located at a distance r = 60 mm from its geometric center C. The centroidal radius of gyration of the wheel is k = 90 mm. As the wheel rolls without sliding, its angular velocity is observed to vary. Knowing that ω = 8 rad/s in the position shown, determine (a) the angular velocity of the wheel when the mass center G is directly above the geometric center C, (b) the reaction at the horizontal surface at the same instant.
