How to Evaluate Speed Ratio of Compound Gear Train?

Speed Ratio of Compound Gear Train evaluator uses Velocity Ratio = Product of Number of Teeth on Driven/Product of Number of Teeth on Drivers to evaluate the Velocity Ratio, Speed Ratio of Compound Gear Train is the product of the gear ratios of each gear pair in the train. It is calculated by multiplying the individual gear ratios, where each gear ratio is the ratio of the number of teeth on the driving gear to the number of teeth on the driven gear. Velocity Ratio is denoted by i symbol.
