SUMMARY
The discussion focuses on calculating the necessary spacing for bridge expansion due to temperature changes, specifically using a linear expansion coefficient of 1.2 × 10-5(°C)-1. The formula used is ΔL = L0αΔT, where L0 is the original length (76 m), α is the linear expansion coefficient, and ΔT is the temperature change (69°F, converted to Celsius). The correct calculation results in a required spacing of 3.48 cm, highlighting the importance of unit conversion in engineering calculations.
