⛰️ Water-Powered Canal Incline: Trolleys, Sluice Power and Governor (2D side view)

Side view of a water-driven canal incline with two counterbalanced trolleys. Set sluice opening, head, and the cargo on each trolley, and watch cable speed, force balance and position as flow power fights gravity, rolling resistance and drag. Same physics file as the 3D page, with four in-page numerical checks.
