Frequently Asked Questions (FAQ)
What is the Linear Thermal Expansion Calculator (ΔL = α L₀ ΔT) and how does it work?
Civil, mechanical, and materials engineering tool. Determines required expansion joint gap for piping, bridges, and railway tracks.
How do I use this Linear Thermal Expansion Calculator (ΔL = α L₀ ΔT)?
Enter Initial Length ($L_0$ in meters). Select or Enter Linear Thermal Expansion Coefficient ($\alpha$, e.g. Steel = $12 \times 10^{-6}$ /°C). Enter Temperature Change ($\Delta T$ in °C). View Elongation / Length Shift (ΔL in mm).
What mathematical formula is used in this calculation?
Length Variation ΔL = α * L0 * ΔT. Final Length L = L0 + ΔL. α in 1/°C.
