Motion Transformation Systems
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
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 https://www.youtube.com/watch?v=zleZSKYBWWg
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 https://www.youtube.com/watch?v=ZbdsGf_t8hs
4. Screw gear system Nut is driver and the screw (rotational motion into translational motions) Or vice –versa, screw is driver. Ex car jacks
