The fixed ring gear lies in the horizontal plane. The hub and planet gears are bonded together. The mass and moment of inertia of the combined hub and planet gears are, mHP = 130 kg and IHP = 130 kg-m2 The moment of inertia of the sun gear is Is = 60 kg-m2 The mass of the connecting rod is 5 kg, and it can be modeled as a slender bar. If a 1 k N-m counterclockwise couple is applied to the sun gear, what is the resulting angular acceleration of the bonded hub and planet gears ?
