🚜 Forklift Yard Drive: Friction Circle, Roll and Tip Margin (2D top-down view)

2D top-down yard view of a forklift with a rear-view tip gauge. Steer and throttle it yourself while changing payload mass, load height and offset, mast lift, slope and tyre friction, and watch roll, tip margin, the friction circle and the energy use. Same vehicle dynamics module as the 3D page, with five in-page numerical checks.
