The schematic diagram of a centrifugal governor is shown in Fig. 2.70. The length of each rod is l, the mass of each ball is m, and the free length of the spring is h. If the shaft speed is ω determine the equilibrium position and the frequency for small oscillations about this position.
it is well known that wind makes cold air feel much colder as a result of the wind-chill effect which is due to the
