🌡️ Thermal Expansion of a Rod (2D)

Interactive 2D simulation of linear thermal expansion. Pick a real material (steel, aluminum, glass, brass or invar), change temperature, and watch a rod grow or shrink using the real formula ΔL = L0·α·ΔT.

⚙ Under the hood

A 2D canvas simulation of linear thermal expansion in a rod. Choose a real material — steel, aluminum, brass, glass or invar — change the temperature, and watch the rod grow or shrink live using the real formula ΔL = L0·α·ΔT with each material's true expansion coefficient.
