HW10 In an engine governor of the Porter type, the upper and lower arms are 230 mm and 330 mm respectively and pivoted on the axis of rotation. The mass of the central load is 13 kg, the mass of each ball is 1.5 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 40° and 55°, find, taking friction into account, the range of speed of the governor and Sensitiveness of Governors.
