Question 1

What is a Thermal Expansion Calculator?

Accepted Answer

Thermal expansion describes how materials change size with temperature. Most solids expand when heated and contract when cooled. Linear thermal expansion: ΔL = α × L₀ × ΔT, where α is the material's coefficient of thermal expansion.

Question 2

How does the Thermal Expansion Calculator work?

Accepted Answer

Linear expansion: ΔL = α × L₀ × ΔT Then: Volumetric expansion: ΔV = β × V₀ × ΔT ≈ 3α × V₀ × ΔT Then: α (steel) ≈ 12 × 10⁻⁶ /°C · α (aluminium) ≈ 23 × 10⁻⁶ /°C · α (concrete) ≈ 12 × 10⁻⁶ /°C.

Question 3

Can you give an example of how to use the Thermal Expansion Calculator?

Accepted Answer

Example: Input Steel rail 10m long · temperature rise 50°C gives a result of ΔL = 6mm (12×10⁻⁶ × 10 × 50 = 0.006m).

Question 4

Is the Thermal Expansion Calculator free to use?
