A flyball governor is a device used to regulate the speed of steam turbines in steam power plants. The rotation of the shaft causes the two balls move outward. As the balls move out, they pull on the bearing A. The position of the slider A is linked to a valve admitting steam into the turbine. This way, the flow of speed is automatically restricted when the shaft starts rotating too fast.
The following data is given for the flyball governor shown in the figure:
L =300 mm
gama= 45 degrees
m = 1 kg (the mass of each ball)
N = 1452 RPM
What is the force (in N) pulling on the slider A if the shaft rotates at the speed given below? Ignore friction and the weights of the conmponents other than the two balls.
I have NO idea where to start with this one! Everything I do just seems to lead in circles and not get me anywhere...Any help would be much appreciated...
