Thanks for ur reply, ΔL = α*L* ΔT ΔL = 7.3 * 10^-6 * 90* 12 *(95-15) = 0.63 inch Here I considered temperature change between expected extremes

The question is for engineering exam, the location of the gap is at support, if we consider the temperature change is between the two extremes, we will get a value doesn’t match with any of the available choices

Hi guys, Would you please help me with this question: steel bridge girders are set in place on their bearings when the ambient temperature is 65°F. if the temperature of the steel is expected of 15°F and 95°F . what is most nearly the expansion gap that must be provided at the bearings? select...
