In an engine governor of the Porter type, the upper
and lower arms are 200 mm and 250 mm
respectively and pivoted on the axis of rotation.
The mass of the central load is 15 kg, the mass of
each ball is 2 kg and friction of the sleeve together
with the resistance of the operating gear is equal
to a load of 24 N at the sleeve. If the limiting
inclinations of the upper arms to the vertical are
30° and 40°, find, taking friction into account,
range of speed of the governor.
