Today I am introducing “Four bar mechanism made of paper”
The four-bar mechanism is very useful in the design of mechanical components. The best way to understand four-bar mechanisms is to build it by yourself. Here, I am introducing how to make a four-bar mechanism with only a paper, screws and nuts. It is very easy to follow.
If you want to know the theories of four-bar mechanisms, see the wiki. Here
1. What you need to prepare
One sheet of paper, four screws and nuts, and a nail (or any sharp one)
- Prepare a sheet of paper
- Tear the paper like this
- Fold two times
- Write numbers like the picture
- Make holes
- Now you should have four bars with eight holes
- Connect bars. Here the sequence is very important. If you do not follow this sequence the linkage will not rotate because interference with other linkages.
- Connect all
- Hold (4) and rotate (1)
This is the result.
This is a Grashof mechanism.
So far, I have introduced how to build a four-bar mechanism made of paper. I hope that this post helps your projects. If you have any question, please leave a reply.
