Thermal Expansion

Theory & Logic

Theoretical Background

Physics describes the fundamental mechanism of the universe. The Linear Thermal Expansion is an essential tool for understanding Linear Thermal Expansion in quantitative terms. Calculate ΔL = α * L0 * ΔT.

Mathematical Formulation

The relationship between the variables is governed by the following equation:

Result = alpha × l0 × dt
Eq 1.1: Governing Formula

Variable Legend

Symbol Parameter Unit
alpha Expansion Coeff (α) 1/K
l0 Initial Length m
dt Temp Change K

Practical Calculation Example

Problem

Calculating the result when:

  • Expansion Coeff (α) = 10 1/K
  • Initial Length = 55 m
  • Temp Change = 45 K

Solution

Substituting into Eq 1.1:

Result = 10 × 55 × 45
