Firefighters use it because the knot balances friction and tension perfectly. Once tightened, the rope’s pressure distributes evenly across the hitch, locking it in place without slipping, even under extreme loads. It’s quick to tie, easy to release, and strong enough to save lives. That’s physics doing it

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
