The pitch circle diameter of the annular gear in the epicyclic gear train shown in Fig.15.9 is 425 mm
and the module is 5 mm. When the annular gear 3 is stationary, the spindle A makes one revolution in
the same sense as the sun gear 1 for every 6 revolutions of the driving spindle carrying the sun gear.
All the planet gears are of the same size. Determine the number of teeth on all the gears.
