#3. A) Give an example of how the concept of thermal expasion is important for construction B) The thermal linear expansion coefficent for concrete is 12 x 10-6 /°C. In lab we saw that AL = aL‚AT. We also discussed how the thermal expansion is doubled for area expansion. If a thin concrete slab measuring 2.1 m² is heated from 40 °F to 83 °F, how much will its area expand (ignoring vertical expansion)?
