The pinion located at "a" in Figure 2 (a) rotates at 850 revolutions per minute, and transmits 11 kW to idler gear 3. The gears have a module of 3, and a 21 degree pressure angle. Calculate the speed of rotation of gear 4. Determine the torque that is generated at gear 4. O o Determine the resultant, tangential and radial forces that act on idler O O gear 3 from the pinion. Sketch the forces that act on idler gear 3 from the pinion. (15 marks) ------- a 600 b 34 teeth ******** ------ 17 teeth 32 4 51 teeth Figure 2 (a)
