    • The coefficient of expansion for steel is approximately 12 × 10⁻⁶ per degree Celsius.
    • Engineers must consider the coefficient of expansion when designing bridges to prevent buckling.
    • Different materials have different coefficients of expansion, which affects their use in construction.
