The roadway of the golden gate bridge is 1320 m long and it is supported by a steel structure. If the temperature varies from -30C to 39C. how much does the length change? the result indicate the size of the thermal expansion joints that must be built into the structure. Without the joints the surfaces would buckle on very hot days or crack due to contraction on very cold days.

2) Give atleast two additional examples where the thermal expansion must be taken into account when designing structures or devices?
