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.
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 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 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 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
Wheels and Pulleys
In this class we will explore the potential of wheels and pulleys for kinetic machines
Combined Cyclic Motion
Models and Tools
Looms and Logic
In this class we will explore the potential of looms for computing with thread
