What is thermal expansion?
Remember the common materials that expand when heated.
Expansion joints are used in which structures?
Think about structures that experience temperature fluctuation.
A 50 m long railway steel beam is exposed to a temperature rise of 20°C. Calculate the new length if its coefficient of linear expansion is 11 × 10⁻⁶ °C⁻¹.
Remember to apply the linear expansion formula correctly.
Discuss the consequences of thermal expansion on bridges and how engineers mitigate these effects.
