Placing the Fulcrum on a Seesaw

The video tutorial explores a physics problem involving a seesaw with a movable fulcrum. The problem is set up using a meterstick, masses, and a domino. The tutorial covers creating a free-body diagram, analyzing forces, and applying static equilibrium principles to solve for the fulcrum's position. The solution demonstrates that the system balances at the 45 cm mark, and the tutorial concludes with insights on problem-solving techniques.
