If gear A turns at 300 rpm, how fast will gear C turn if they have the same number of teeth?

When two gears are interconnected and have the same number of teeth, they will rotate at the same speed. This is because the rotation of one gear directly impacts the rotation of the other. In this case, if gear A is turning at 300 revolutions per minute (rpm), and gear C has the same number of teeth, it means that gear C will also complete the same number of rotations in a given period of time. Therefore, gear C will also turn at 300 rpm.

Understanding the relationship between gear sizes, teeth count, and rotation speed is essential in mechanics. Gears typically transmit motion and force through interlocking teeth, and when they share the same number of teeth, they essentially move together in synchronization, resulting in identical speeds. This concept is fundamental in gear mechanics and helps explain the behavior of systems involving multiple gears.
