A wheel of mass and radius is made of a thin uniform distribution of mass at the rim and a point mass at the center. The spokes of the wheel are massless. The center of mass of the wheel is connected to a horizontal massless rod of length , with one end fixed at , as shown in the figure. The wheel rolls without slipping on horizontal ground with angular speed . If is the total angular momentum of the wheel about , then the magnitude . The value of (in integer) is:
