Question 2: The pinion located at "a" in Figure 2(a) rotates at 850 revolutions per minute, and transmits 11kW 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. - Determine the resultant, tangential and radial forces that act on idler gear 3 from the pinion. - Sketch the forces that act on idler gear 3 from the pinion.
