250 m m. h Q2. (10 marks) A piece of metal of a long bridge has initial length 250 m. It is broken in two pieces of equal length when heated. The coefficient of linear expansion of this metal is 12 x 10Ⓡ (°C)! When the pieces bend, they rise h=2.74 m (Fig. 2). Find the increase of temperature. m Fig. 2
