A gap must be left between steel

rails to allow for thermal expansion .

How large a gap is needed if the

maximum temperature reached

is 50 ° above the temperature at

which the rails were laid . The

length of the rail is 10 m and

the α_{steal} = 12 \times 10^{- 6} / ° c

10 \times 12 \times 50 \times 10^{- 6} = 0.006 m = 6 m m
