Wood is kind of pretty hard and the chain of the chainsaw is made of “blocks” I suppose, can’t really find out what it exactly is but anyway, to me, it seems like that chain would just get stuck in the wood at the very moment it touches it. Even more when cuting deeper into the tree.
In: Engineering
Key is the speed. Try it with a barely moving chain and it gets stuck. Get enough speed and the wood it gets stuck in can’t hold it and breaks, allowing the next block to eat a little more inside.
As the saw goes in, it goes in a straight plane and touches nothing else. From the saw perspective, it’s just the wood below it that is present. The rest doesn’t offer resistance. Also the sides of the blocks are relatively flat and can slide should there be a small misalignment. But torque it enough and it will surely Jam.
Edit key is the speed. Not isn’t.
