How Gear Ratio s work. You see gears in just about anything that has spinning parts -- car engines, transmissions, VCRs Learn what these gears are doing and get to the bottom of the "gear ratio" concept!

Gear train. For the wide-ratio transmission, the first gear ratio is 4:1 or 4, and in second gear it is 2:1 or 2, so the progression is equal to 4/2 = 2 (or 200%). For the close-ratio transmission, first gear has a 4:1 ratio or 4, and second gear has a ratio of 3:1 or 3, so the progression between gears is 4/3, or 133%.

What is a gear ratio? (with picture. A gear ratio is the relationship between the number of teeth on two gears which are meshed. This relationship is expressed mathematically. For example, if one gear with 13 teeth is driven by a gear with 21 teeth, the gear ratio is 1/1.62, or 1:1.62.
