1. Motion Transformation Systems

2. 1. Slider and Crank
Motion of crank is transmitted to the connecting rod
Transforms rotational motion into translational motions
Motion is then transmitted to another part.
Ex. Gas engines, pumps

3. 2. Rack and Pinion Rack (straight rod with teeth), gear (pinion)
Motion transformed by motion of the teeth.
Translational to rotational or vice-versa
Needs lubrication, no slipping ex. Steering systems, microscopes

5. 3. Cam and Follower Irregular shaped disk, rod called a follower
When cam turns, follower makes translational motion (up and down)
Sewing machines, toys, motor valves

6. 4. Screw gear system
Nut is driver and the screw (rotational motion into translational motions)
Or vice –versa, screw is driver. Ex car jacks
