When the Gateway Arch in
St. Louis was being constructed,
the workers were installing the final segment at the top, but
the gap was too small for it to
fit. The 25 foot section was .25" too large. To make the
segment
fit, workers actually sprayed the two 600 foot sides down with water to cool them using the
principle of thermal expansion. If the Arch is constructed of stainless
steel, which has a coefficient of .00000876, what temperature decrease did the
workers have to get the sides to achieve for the segment to fit?
