A double-decker London bus might be in danger of rolling over in a highway accident, but at the low speeds of its urban environment, it’s plenty stable. The track width is 2.05 m. With no passengers, the height of the center of gravity is 1.45 m, rising to 1.73 m when the bus is loaded to capacity. What are the critical angles for both the unloaded and loaded bus?
