The speed of the pickup truck’s engine is controlled by the Porter governor with 4 arms of equal length, and pivot on the axis of rotation. Each ball has a mass of 4 kg and the mass of the central load on the sleeve is 20 kg. The radius of rotation of the ball is 150 mm when the governor begins to lift, and 200 mm when the governor is at maximum speed. The initial angular speed of the engine’s crank is 14 rad/s, and it has reached a maximum speed at an acceleration of 0.4 rad/s2 after 5 seconds. a) If the speed of the crank of an engine is equal to the speed of its governor, calculate the angle between the upper arm and axis of rotation (?) when the governor starts to lift and when it is at maximum speed. b) Prove that the length of the governor’s arms is equal

Question
The speed of the pickup truck’s engine is controlled by the Porter governor with 4 arms of equal length, and pivot on the axis of rotation. Each ball has a mass of 4 kg and the mass of the central load on the sleeve is 20 kg. The radius of rotation of the ball is 150 mm when the governor begins to lift, and 200 mm when the governor is at maximum speed. The initial angular speed of the engine’s crank is 14 rad/s, and it has reached a maximum speed at an acceleration of 0.4 rad/s2 after 5 seconds.
a) If the speed of the crank of an engine is equal to the speed of its governor, calculate the angle between the upper arm and axis of rotation (?) when the governor starts to lift and when it is at maximum speed.
b) Prove that the length of the governor’s arms is equal
