True or false: A gear ratio always describes the gear doing the driving acting upon the gear being driven.

Understand the Problem

The question is asking whether the statement about gear ratios is true or false. It highlights the relationship between the driving gear and the driven gear in terms of gear ratios.

More Information

In mechanics, a gear ratio refers to the relationship between two gears in terms of their rotational speeds. It specifically describes how the driving gear, or input gear, affects the driven gear, or output gear. This ratio defines how power and speed are transmitted through the gear system.

Tips

A common mistake is misunderstanding which gear is the driver and which is the driven gear. Always ensure you identify the input (driving) and output (driven) gears correctly.
