2. What is a motion transformation system?
It is a system that turns one type of motion into another. Most of the time, there devices transform a rotational motion into a translation motion, or vice versa.

3. Examples of motion transformation systems
Rack and pinion
Cam and follower
Connecting rod and crank
Examples of motion transformation systems

4. Rack and pinions
It is made up of a toothed wheel (pinion) and a straight toothed rod (rack).
When the pinion is rotated, it moves the rack because the teeth of the two parts fit into each other.

6. Cam and follower
Transform a rotational motion into a bidirectional translational motion.
A cam is a part that is oval- shaped, or that rotates off- centre.

8. Connecting rod and crank
The crank is the part that rotates, while the connecting rod is a bar or stem attached to the crank.
