The humber bridge in england has the world's longest single span, 1410 m . calculate the change in length of the steel deck of the span when the temperature increases from -3.0 ∘c to 18.5 ∘c.
Applicable linear expansion equation: ΔL = αΔTL In which ΔL = change in length, α = Linear expansion coefficient of steel, ΔT = change in temperature, L = original length
Therefore, ΔL = 12*10^-6*(18.5-(-3))*1410 = 0.36378 m
