What should a literature review of a teeter-totter contain?
Some more info would be useful, you know.
I think of:
- different types of titter-totters.
- mechanisms to make the "springback" (e.g. springs, simple lever w/ gravity,...)
- a mathematical model of the types (spring-mass system or lever system)
You can also write a poem on them, if you wish.
Separate names with a comma.
