How Everything Works on Instagram: "A smart use of physics makes the tough job of removing a tree stump much easier. By wrapping a chain around both a large tire and the stump, the setup turns into a simple machine that applies engineering principles to everyday problem-solving. This trick cleverly multiplies force through leverage. The tire acts like a moving fulcrum. As a vehicle pulls the chain, the tire rolls forward, redirecting the horizontal pull into upward force. This vertical lift help
