Two identical 125 m spans of a bridge are placed end to end so that there is no room for expansion. Since there is no expansion joint between them, they are pushed into a final position as shown after the temperature is increased by 20.0 degree C. What is the coefficient of linear expansion of the beams if the angle theta between the final and initial position of the beams is 1.26 degree. Be very accurate here.

FQ4 Two concrete slabs of a 250m bridge are assembled without
any space between them, as in the figure below the left. After a
rise in the ambient temperature of 20 ° C, the contact region
between the plates rises to a height y, as indicated in the figure
below, to the right. Calculate the value of y. The linear expansion
coefficient of the concrete is 12E-6
