Historical Farm Cart Physics: Hay vs. Stone Load Comparison #124248 (License: Personal Use)

This detailed ink illustration depicts two wooden-wheeled farm carts ascending a gentle incline: the left cart carries a large,蓬松 (bulky) bale of hay, its center of gravity high and rearward; the right cart holds compact stones, lowering its center of gravity and improving traction. Dashed vertical lines indicate the projected centers of mass, demonstrating why stone-laden carts were less prone to tipping on steep terrain. The image reflects practical agrarian engineering from the late 1800s.
