A highway is made of concrete slabs that are 16.2 m long at 20.0°C. Expansion coefficient of concrete is α = 12.0 × 10−6 K−1. A) If the temperature range at the location of the highway is from −20.0°C to +36.9°C, what size expansion gap should be left (at 20.0°C) to prevent buckling of the highway? in mm B) If the temperature range at the location of the highway is from −20.0°C to +36.9°C, how large are the gaps at −20.0°C? in mm
