Asked by Danny
                Calculate the amount of expansion occurring when a steel rail 920.000 meters in length is heated from -10.000 to 410.000 degrees Celsius.
ANS = m
Steel = 12 * 10 ^-6
= 0.000012
Change in length
= Original length * Coefficient of linear expansion * Temperature rise.
= 920m * 0.000012 * 420
ANS = 4.636m
Please Check, Thank you.
