Computing with Thread: Part II
Levers and Cranes
In this class we will explore the potential of levers and cranes for kinetic machines
The fundamental law of threads
You can pull something with a string, but you can't push it.
That's common sense. And no computer knows it.
(Marvin Minsky)
Threads between two points
Using a threads to transmit information:
- stick: symmetric with respect to push and pull
- thread: pull, yes. push, no.
- Can you build an anti-thread? (i.e. pull no, push no)
Sliders
Sliders are bars that connect transmit a motion by sliding back and forth
- Getting to know the concept of degrees of freedomn
- How can we make sure a bar only goes back and forth?
- What other constructions can you think of?
- What kind of constraints are imposed by your constructions?
Levers
Levers are bars that transmit a motion by rotating around a hinge
- What practical applications of levers can you think of?
- Explore different setups and their properties
- How many points are involved, and how are they arranged?
- How many different setups can you find?
- How are the involved forces and distances related?
- Which setups are suitable for which purposes?
Linkages
Linkages are bars that are connected via hinges.
- how would you create rotating hinges using bars of wood and screws?
- can you create a hinge using thread and what are the limitations?
- create a linkage that can draw interesting curves
