313 m-You need to specify the coefficient of linear expansion to solve this problem.-dL = Lo*α*dT = 518*11E-6*(35 - (-20)) = .......
between temperature extremes of -20°C and 35°C?

-
The equation for linear expansion (e) is ..

e = Lo.α.∆θ .. (in m)

α = coef.of linear expansion
Lo = original length in m
∆θ = temperature change in ºC

e = (518)(11.0^-6)(55) .. .. ►e = 0.313 m

You need to specify the coefficient of linear expansion to solve this problem.

dL = Lo*α*dT = 518*11E-6*(35 - (-20)) = .313 m
