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
