@monte0580: Train wheels aren’t perfectly cylindrical. That slight taper means the outside wheel can cover more distance than the inside wheel on a curve, even though both are fixed to the same axle. It’s a simple bit of geometry that helps the wheelset guide itself through the curve. Did you know train wheels worked like this? #railway #Science #funnycat #LearnOnTikTok #fyp
