Estimate the torque needed to initially rotate the object. Consider a composite object consisting of 2 identical spheres of radius as connected by a thin cylindrical rod of length l and radius ac, where l ? ac. The spheres are widely spaced. The object is set to rotate about an axis perpendicular to the plane of the spheres. The object is initially accelerated with an angular acceleration of d?/dt. Neglect the influence of the connecting cylinder.
