City Guilds Model Questions Vol1 2020 Engineering Question 10
Practice objective / multiple choice question 10 from the 2020 City Guilds Model Questions Vol1 Engineering examination.
A steel rod \(2.0\) m long at \(20^{\circ}\)C is fitted into a steel tube whose inner length at the same temperature is \(2.001\) m. The coefficient of linear expansion for steel is \(12 \times 10^{-6}\ \text{°C}^{-1}\). Assuming uniform expansion and neglecting any clearance beyond the initial \(1\) mm, determine the maximum temperature increase (in \(^{\circ}\)C) the assembly can tolerate before the rod no longer fits.
