Two concrete spans of a L = 270 m long bridge are placed end to end so that no room is allowed for expansion (Fig. P10.55a). If the temperature increases by T = 21.0°C, what is the height y to which the spans rise when they buckle (Fig. P10.55b)

2. Relevant equations

change in L/L= average coefficient of expansion(change in T)

average coefficient of concrete= 12 X 10^-6

3. The attempt at a solution

I tried doing

change in L/270= 12 X 10^-6 (21)

I got change in L, and now I dont know what to do. HELP
