a) Pinion 2, which is located on shaft "a", rotates at 1800 rpm, and transmits 75kW to the idler gear 3 located on shaft "b", refer to Figure 6(a). The pinion has a pitch diameter of 85 mm, and the idler has a pitch diameter of 170 mm. The pressure angle of the teeth is 20 degrees. 3 :00 Figure 6(a) i.The pinion has a module (modular pitch) m = 2.5. Determine how many teeth are on both the pinion and gear 3. (4 marks) ii.Using a diagram to support your answer, explain the term "circular pitch" and calculate the circular pitch for the pinion. (6 marks) iii.Determine the tangential and radial forces that act on gear 3 from the pinion and show both these forces on a free body diagram. iv.Calculate the torque that is generated by pinion 2.
