The epicyclic gear train consists of the sun gear A which is in mesh with the planet gear B. This gear has an inner hub C which is fixed to B and in mesh with the fixed ring gear R. If the connecting link DE pinned to B and C is rotating at ωdl =18 rad/s about the pin at E, determine the angular velocities of the planet and sun gears.
