In an epicyclic gear train (Fig.15.41) an annular wheel 'A' having 54 teeth meshes with a planet wheel 'B' which gears with a sun wheel 'C', the wheels 'A' and 'C' being co-axial. The wheel B is carried on a pin fixed on one end of arm P which rotates about the axis of the wheels A and C. If the wheel A makes 20 rpm in a clockwise sense and the arm rotates at 100 rpm in the anticlockwise direction and wheel C has 24 teeth, determine rpm and sense of rotation of the wheel C.
