3 A parallel helical gearset consists of a 19-tooth pinion driving a 57- 3×3=9 tooth gear. The pinion has a left-hand helix angle of 30°, a normal pressure angle of 20°, and a normal module of 2.5 mm. Find: (a) The normal, transverse, and axial circular pitches (b) The transverse diametral pitch and the transverse pressure angle (c) The addendum, dedendum, and pitch diameter of each gear
