1. Transformation Systems

2. Transformation System  A transformation system transforms one type of motion into another type of motion  Connecting rod and crank  Translation to rotation  Cam and follower  Rotation into translation  Rack and pinion  Rotation into translation  Screw and nut  Rotation into helical

3. Connecting rod and crank (with piston)  Transforms translation into rotation. A piston usually pushes the connecting rod which turns the crank. Piston Connecting rod Crank

4. Example  Combustion engine  Steam engine https://www.youtube.com/watch?v=73txXT21aZU https://www.youtube.com/watch?v=73txXT21aZU

5. Cam and follower  Transforms rotation into translation  The cam rotates and the follower traces the contour Cam Follower
