An aluminum and an iron bar are of unequal length. An iron bar whose length is 60.00 meters is at 0 degrees Celsius. An aluminum bar whose length is 60.05 meters is at +10 degrees Celsius.
Find a temperature at which they are the same length. The coefficient of expansion of iron is 11 E -6 per C degree.
The coefficient of expansion of aluminum is 24 E -6 per C degree.
