Introduction
Total Quality Management (TQM) is a concept created by W. Edwards Deming. It was originally introduced in Japan after World War II to assist the Japanese in re-building their economy.…
Effort and Power of a Governor
The effort of a governor is the mean force exerted at the sleeve for a given percentage change of speed (or lift of the sleeve). It may be noted that when the…
Hartnell Governors
Hartnell governor is a spring controlled centrifugal governor, in which a spring controls the movement of the ball and hence the sleeve. Above fig shows a Hartnell governor. It consists…
Isochronous Governors
An isochronous governor having structure which provides a pressure force to compensate for the relative decrease of governor spring force with respect to flyweight force as engine load increases, thereby…
Sensitiveness of Governors
Consider two governors A and B running at the same speed. When this speed increases or decreases by a certain amount, the lift of the sleeve of governor A is…
Instantaneous centre method
In this method, equilibrium of the forces acting on the link BD are considered. The instantaneous centre I lies at the point of intersection of PB produced and a line…
Method of resolution of forces
Considering the equilibrium of the forces acting at D, we have Again, considering the equilibrium of the forces acting on B. The point B is in equilibrium under the action…
Porter Governor
The Porter governor is a modification of a Watt’s governor, with central load attached to the sleeve as shown in Fig. 5.3 (a). The load moves up and down the…
