Not quite seaver... its 1.24 x10-5
The equation for linear expansion is ∆L= α L0 ∆T
Change in length equals the thermal coefficient for the material, times the initial length, times the change in temperature in degrees C (or K).
The thermal coefficient of steel is 1.24x10-5, so for every degree C change, the steel expands by 1.24x10-5 %. So to expand the 60 foot steel girder, that’s
0.5 = 1.24x10-5 * 60 * ∆T
∆T = 672.04 C
Well within the 1000C range I have to work with.
