A class 2 lever puts the the fulcrum on on end, the load on the other, and the effort somewhere in between.
This project illustrates this fundamental tool while also delivering some high-flying projectiles!
Tools and Materials
Testing:
- 5lbs+ of weight
- A large, flat object to create gusts of wind
Tips and Troubleshooting
If the hinge is breaking or falling out of the cubes, then...
- Just use 1 rubber band. 2 or more may put too much strain on the dowel
- Make the dowel slightly longer so it can't fall out from between the cubes with holes
