Understanding Buckling!

viral || sci || physics || universal on Instagram: "Track buckling happens when a section of railway track bends or warps out of alignment, usually due to extreme heat. Steel rails expand when temperatures rise, and if there isn’t enough room for that expansion (because the rails are tightly fixed in place), the built-up pressure can cause the track to shift sideways or form waves. This can be dangerous because trains depend on perfectly aligned rails to stay stable. To prevent buckling, railway
