Two concrete spans that form a bridge of total length L0 = 314 m when the temperature is T0 = 68^oF, are placed end to end so that no room is allowed for expansion. If the temperature rises to T = 104^oF, the The two spans after expansion will buckle. Determine the amount h that the middle of the bridge will rise by. Hint: Think about using the Pythagorean Theorem here.

(a) 1.44 m

(b) 1.94 m

(c) 2.44 m

(d) 2.94 m

(e) 3.44 m

(f) None of the above.
