🏛️ London Landmarks Structures: Arches, Towers and the Giant Wheel

Four lab stops on pontoons in a 3D stylised Thames with the Westminster skyline behind them: a stone arch with a draggable vehicle and its line of thrust, a clock tower bending in the wind, a pre-tensioned spoked giant wheel whose cables go slack, and a suspension cable (parabola, catenary and a Verlet chain). Real statics, eight analytic-versus-numerical checks, quests and a collapsible science panel.
