Fulcrum Freight

Place the freight. Balance the moment.

Select a crate:

Selected crate position

Assign the three crates to distinct meter marks. The left and right gravitational moments must cancel. Release the beam; hold its tilt within 3° for 3 seconds during the eight-second trial. Reset returns to editing while keeping placements.

Model, controls & source

Uses crashcat MIT solid-box inertia tensors and parallel-axis translation to compute the loaded beam rotational inertia. Original pivoted-beam integrator and balancing missions. The suspended crates provide restoring torque; the ideal bearing has viscous drag.
