Meriam, Kraige & Bolton — Plane Kinetics of Rigid Bodies: Problem 6_101

6/101 The 20-kg wheel has an eccentric mass which places the center of mass G a distance \(\bar{r} = 60\text{ mm}\) away from the geometric center O. A constant couple \(M = 6\text{ N}\cdot\text{m}\) is applied to the initially stationary wheel, which rolls without slipping along the horizontal surface and enters the curve of radius \(R = 600\text{ mm}\). Determine the normal force under the wheel just before it exits the curve at C. The wheel has a rolling radius \(r = 100\text{ mm}\) and a radius of gyration \(k_O = 75\text{ mm}\).
