Practice objective / multiple choice question 48 from the 2024 City Guilds Model Questions Vol1 Engineering examination.
A steel pipe (inner diameter 200 mm, outer diameter 220 mm) is installed in a concrete wall opening (inner width 202 mm, outer width 222 mm) at 20 °C. The coefficients of linear expansion are \(\alpha_{steel}=12\times10^{-6}\,°C^{-1}\) and \(\alpha_{concrete}=10\times10^{-6}\,°C^{-1}\). Assuming uniform temperature increase, at what temperature rise (in °C, rounded to the nearest whole number) will the inner clearance become zero? State the temperature increase required.
