However, the two gears can vary in size to achieve a different gear ratio. An example of this is in a hand drill, where the drive gear is larger than the driven gear. A pillar drill with a rack ...

Learn how Lego Technic gear ratios work in this detailed explanation. This video breaks down the process, showing how different gear combinations affect speed and torque.

For example, a low gear ratio on a bike or car. If the driven gear is made smaller it will rotate more quickly but with a smaller moment. For example, a high gear ratio on a bike or car.
