Lever simulator in 3D for the three classes of levers: move the fulcrum and change the masses and the distances of the effort and the load until the lever balances with the law of the lever, M₁ = M₂. If one side is heavier, the plank really tips over to its stop, and the panel works out F = m·g and both moments. With a challenge mode to practice.
