The system shown is in equilibrium when f 5 0. Knowing
Chapter 13, Problem 13.67(choose chapter or problem)
The system shown is in equilibrium when f = 0. Knowing that initially \(f = 90^{\circ}\) and that block C is given a slight nudge when the system is in that position, determine the speed of the block as it passes through the equilibrium position f = 0. Neglect the weight of the rod.
