What is the gear ratio of a system with gears having the following configurations: 10t, 20T, 15T, and 30T?

To determine the gear ratio for a system with gears having 10 teeth, 20 teeth, 15 teeth, and 30 teeth, it is essential to understand how gear ratios are calculated based on the number of teeth on the gears involved.

The gear ratio is defined as the ratio of the number of teeth on the driven gear (the gear that is turned by the motor or driving gear) to the number of teeth on the driving gear (the gear that is providing the input). In this case, if we look at the pairs of gears, we can find the ratio for each pairing.

For example, if we were to consider the gear pairings as follows:

• 10 teeth driving a 20 teeth gear gives us a ratio of 20:10, which simplifies to 2:1.

• Additionally, if we consider 15 teeth driving a 30 teeth gear, the ratio here would be 30:15, simplifying to 2:1 as well.

However, if the gears can be connected in such a manner that multiple stages are utilized, one can multiply the individual ratios.

When combining the effects of both gear sets, if you establish the first pair and then utilize the second pairing in sequence, one
