Question: Consider the same conditions as for Sample Problem 4/2, except that the spokes are freely hinged at (O) and so do not constitute a rigid

Consider the same conditions as for Sample Problem 4/2, except that the spokes are freely hinged at \(O\) and so do not constitute a rigid system. Explain the difference between the two problems.

m F- Hinge y m b 120 120 r x m

Problem 4/2,

Each of the three balls has a mass \(m\) and is welded to the rigid equiangular frame of negligible mass. The assembly rests on a smooth horizontal surface. If a force \(\mathbf{F}\) is suddenly applied to one bar as shown, determine (a) the acceleration of point \(O\) and \((b)\) the angular acceleration \(\ddot{\theta}\) of the frame.
