Total Downward Force on Sleeve in Wilson-Hartnell Governor

LaTeX Go Force = Mass on Sleeve*Acceleration due to Gravity+(Tension in the auxiliary spring*Distance of Auxiliary Spring from Mid of Lever)/Distance of Main Spring from Mid Point of Lever

Corresponding Radial Force Required at Each Ball for Spring Loaded Governors

LaTeX Go Corresponding Radial Force Required at Each Ball = (Force Required at Sleeve to Overcome Friction*Length of Sleeve Arm of Lever)/(2*Length of Ball Arm of Lever)

Angle between Axis of Radius of Rotation and Line Joining Point on Curve to Origin O

LaTeX Go Angle B/W Axis of Radius of Rotation and Line OA = atan(Controlling Force/Radius of Rotation if Governor is in Mid-Position)

Angle between Axis of Radius of Rotation and Line Joining Point on Curve to Origin

LaTeX Go Angle B/W Axis of Radius of Rotation and Line OA = atan(Mass of Ball*Mean Equilibrium Angular Speed^2)

What is Porter Governor?

Porter Governor is a modification of Watt Governor with a central load attached to the sleeve. This load moves up and down the central spindle. The additional force increases the speed of revolution required to enable the balls to rise to any predetermined level.
