🎡 Treadwheel Hoist: Lever Arm, Walking Force and Lift Speed (2D)

Side view of a human-powered treadwheel crane. Set the number of walkers, wheel and drum radius, load, push force and friction, then watch the wheel turn and the load rise. The mechanical advantage, the heaviest liftable load, the steady lift speed and the energy accounting come from the torque balance on the wheel, with four in-page numerical checks. A mechanics companion to the 3D treadwheel hoist reconstruction.
