Drive gearZG1 = 49ZA1 = 16
Driven gearZG2 = 38ZA2 = 67

i = Z2 : Z1 → Remark
iG = Gear ratio = ZG2: ZG1= 38 : 49 = 0.776
iA = Final drive ratio = ZA2 : ZA1 = 67 : 16 = 4.188
Overall ratio = total ratio = iG x iA = 0.776 x 4.188 = 3.250
1)  Z1 = No. of teeth on driving gear, Z2 = No. of teeth on driven gear
