SUMMARY
The discussion centers on calculating the height that a steel girder rises due to a temperature increase of 32°C, given its length of 3.77 m and a linear expansion coefficient of 12 x 10-6 /°C. The correct calculation involves using the formula for linear expansion, resulting in a height rise of approximately 0.052 m. Participants debated the validity of using the Pythagorean theorem for small differences, ultimately confirming its applicability in this scenario.
