FINNISH POWER JACK
Finnish Power Jack is an Archimedes’ lever. I created this situation to solve the following problem: you are in the middle of a forest with a chainsaw and wedges. You have a heavy-leaning tree, and you have to make it fall in the opposite direction of the lean.

This video intends to show that it is not a mission impossible; you need some ingenuity and physics. First, you cut a supporting beam between your lifting rod and the trunk and cut notches for it, so it won’t slip. Then you cut a notch to the tree and a back cut. After that, you just begin to lift the lifting beam, and the physics will multiply your power, and the tree will fall in the direction you need it to. Think about it, it is a 1000 years old technique, and it still works!
