A steel ruler is calibrated to read true at 17.5Â°C. A draftsman uses the ruler at 38.5 Â°C to draw a line on a 38.5Â°C copper plate. As indicated on the warm ruler, the length of the line is 0.403 meter. Find to what temperature should plate be cooled, such that the length of the line truly becomes 0.403 meter?
