Thank you for the opportunity to help you with your question!

when the temperature changes the the length will change by:

e = Lo.α.∆θ .. (in m)
where
α = coefficient.of linear expansion
Lo = original length in m
∆θ = temperature change in ºC

e = (518)(11.0^-6)(55) .. in .which ,e = 0.313 m

Please let me know if you need any clarification. I'm always happy to answer your questions.
