Question 1074229: Two iron rails, each 50 feet long, are laid end to end with no space between them. During
the summer, the heat causes each rail to increase in length by 0.04 percent. Although this is
a small increase, the lack of space at the joint makes the joint buckle upward. What distance
upward will the joint be forced to rise? [Assume that each rail remains straight, and that
the other ends of the rails are anchored]
