Activity 1.1.3 Gears - VEX
Introduction
You do not have to look far to see gears. You might not think of an object such as acomputer as having a lot of moving parts, but the CD tray on your computer is likelycontrolled by gears. A traditional watch is full of gears. The watch has one source ofpower or input that must move multiple hands continuously and at different speeds.Some watches also keep track of the day of the month. This may be low-tech by
today’s standards, but imagine the challenge of choosing just the right gears to keep
a watch synchronized. In a watch the gears are used to manipulate rotational speed.Gears are also used in many applications to control torque and rotational direction.
