The New River Gorge bridge in West Virginia is a 518-m-long steel arch. How much will its length change between temperature extremes
Thank you for the opportunity to help you with your question!
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)(11.0x10^-6)((31 - (-17)) .. .. ►e = 0.273 m
