Meriam, Kraige & Bolton — Plane Kinetics of Rigid Bodies: Problem 6_170

6/170 The mechanical flyball governor operates with a vertical shaft $O-O$. As the shaft speed $N$ is increased, the rotational radius of the two 3-lb balls tends to increase, and the 20-lb weight $A$ is lifted up by the collar $B$. Determine the steady-state value of $\beta$ for a rotational speed of 150 rev/min. Neglect the mass of the arms and collar.
