Bob built a scale model of the bridge that is 2.637m long at the lowest temperature (T=-45 degrees Celsius) using an unknown material. When the temperature reaches the highest value (T=43 degrees Celsius), he measures again the length of the bridge finding that it has expanded L=5.56mm. Calculate the coefficient of linear expansion and find the material Bob used to make his model.
