Start with a two-gear train. To be able to determine a gear ratio, you must have at least two gears attached to each other â this is called a gear train.. Usually, the first gear is a drive gear attached to the motor shaft and the second is a driven gear attached to the load shaft.. Divide the teeth numbers of the drive and driven gears. The important thing to remember when dealing with gear trains with more than two gears is that only the driver and driven gears (usually the first and last ones) matter. In other words, the idler gears don't affect the gear ratio of the overall train at all.
The Gearing ratio is the ratio of how much a business owes (debt) compared to the total of the debt plus the amount the owners have invested (equity).n the above example the total debt is Â£180,000 and the owners equity is Â£60,000. The Gearing Ratio is given by using the formula = Debt / (Debt + Owners Equity) x 100% = 180,000 / (180,000 + 60,000) x 100% = 180,000 / 240,000 x 100% = 75%.
