Q2/ In the proell governor shown in figure below, the arm ABC is formed in one piece. Each ball has a mass of 1.8 kg and the effect of friction is equivalent to a force of 9N at the sleeve. AB = 150 mm, BC = 50 mm, and BD = 150 mm. Find the magnitude of the central load on the sleeve, if the governor is to rise to its mean position as shown in the diagram when the speed is 120 r.p.m, the portion BC of the lower arm then being vertical. The gravitational effect of the balls must be taken into account. 25 mm B 225 mm A 25 mm
