Two concrete spans of a 234 m long bridge are placed end to end so that no room is allowed for expansion (Figure a). Each span therefore has a length of L0 = 117 m.  If the temperature increases by 17.8 °C, what is the height y to which the spans rise when they buckle (Figure b)? (The coefficient of linear expansion of concrete is 1.20⋅10−51.20⋅10-5  °C−1.)
