Two concrete spans that form a bridge of total length L0 = 314 m when the temperature is T0 = 68oF, are placed end to end so that no room is allowed for expansion. If the temperature rises to T = 104oF, 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.
