As shown below, two thin strips of metal are bolted together at one end; both have the same temperature. One is steel, and the other is aluminium. The aluminium strip is 1 m long while the steel strip is 1.0015 m long. By how much should the temperature of the strips be increased, so that the strips have the same length? Steel Aluminium Note: the coefficient of linear thermal expansion of steel is 12 x 10-6/°C and that of aluminium is 23 × 10-6/°C. Select the closest answer: O 150 °C O 65 °C O 43 °C O 137 °C O 125 °C As shown below, two thin strips of metal are bolted together at one end; both have the same temperature.
