Question 2
The power of a governor is the work done at
Question 3
consider the following statements:
1) The condition of stability of a governor requires that the slope of the controlling force curve should be less than that of the line representing the centripetal force at the equilibrium speed under consideration.
2) For a centrifugal governor when the load on the prime mover drops suddenly, the sleeve should at once reach the lowermost position.
Which of these statements is/are correct?
