Which of the following is a spring controlled governor?
Isochronism in a governor is desirable when
When the speed of governor increases, then
For a given fractional change of speed, if the displacement of the sleeve is high, then the governor is said to be
A spring controlled governor is found unstable. If can be made stable by
The governor is said to be stable when
The governor becomes isochronous when Where F is controlling force, r is radius of rotation for governing balls and a, b are constants.
A governor is said be isochronous when the equilibrium speed is
Consider the following statements: 1. In stationary constant speed engines, the spring-loaded governor mechanism is fitted on the cam-shaft of the engine. 2. Hunting occurs when the governor is not sensitive. 3. Isochronous governors have the same speed over a wide range of governor action. 4. A governor is said to be unstable if the radius of rotation falls as the speed increases. Which of the above statements are correct?
