⚖️ Lever Lab: Three Classes, Mechanical Advantage and Torque Balance (2D)

Side view of a four metre beam on a movable fulcrum with a load and an effort force that you place anywhere along it. See which of the three lever classes you have built, the effort that balances the load, the mechanical advantage, the fulcrum reaction and the way the beam tilts and settles when the forces are not balanced. Static torque balance, the weight of the beam, virtual work and the beam dynamics are checked numerically, with four in-page numerical checks.
