10–29. A pair of 20°, mild-steel gears are to be selected for an application where they need to transfer 1 hp. The pinion drives at 1725 rpm and the gear must rotate as close to 560 rpm as possible. Determine an appro- priate set of catalog gears, from Table 10.7, for this application. 10–50. A gear train is shown in Figure P10.50. The gears have the following properties: N2 = 18 teeth; N3 = 72 teeth and Pa = 10; N4 = 16 teeth and Pa= 8; and Ns = 48 teeth. Determine the velocity of gear 5 as gear 2 drives at 1200 rpm clockwise. Also determine the center distance between gears 2 and 5. 10–52. A gear train is shown in Figure P10.52. The gears have the following properties: N2 = 15 teeth; N3 = 90 teeth and Pa = 16; N4 = 15 teeth; N5 = 75 teeth; Ng = 75 teeth and Pa= 12; N, = 15 teeth; and Ng = 60 teeth and Pa = 8. Determine the velocity of gear 8 as gear 2 drives at 3600 rpm clockwise. Also determine the center distance between gears 2 and 8. Odo
