Centrifugal Governor.mp4
• Examples of flyball governer• All three have three main components• Flying weight• Restraining spring• Mechanical linkage that changes collar or
shaft position as the speed changes
• Consider the flyball governor and if we consider the gravitational force is negligible compared to centrifugal force then there are two forces acting on system-centrifugal force Fc on weights and a downward spring force Fs acting on throttle rod. The reference position r is adjusted to correspond to desired speed.
• Fc depends upon mass m ,peripheral velocity v, downward force of the spring, and the radial displacement R of the mass m
• At balance,• Fc=Fs• Kcw^2=Ks r^2
