The assembly of two 5-kg spheres is rotating freelyabout the vertical axis at 40 rev/min
Chapter 3, Problem 3/240(choose chapter or problem)
The assembly of two 5-kg spheres is rotating freely about the vertical axis at 40 rev/min with \(\). If the force F which maintains the given position is increased to raise the base collar and reduce to \(\), determine the new angular velocity \(\). Also determine the work U done by F in changing the configuration of the system. Assume that the mass of the arms and collars is negligible.
