**Question 6**Railroad tracks made of 1025 steel (\(\alpha = 12 \times 10^{-6} \, \text{°C}^{-1}\)) are to be laid during the time of year when the temperature averages 15°C (59°F). If a joint space of 4.6 mm (0.180 in.) is allowed between the standard 11.9 m (39 ft) long rails, what is the hottest possible temperature that can be tolerated without the introduction of thermal stresses?**Attachments** - Attach File - [Browse My Computer] - [Browse Content Collection]
