Unos rieles de ferrocarril están fabricados con un acero con 0.25 % de C, que posee un coeficiente de dilatación lineal α 1.1 x 10 -5 C-1 y fueron instalados una época del año en que la temperatura promedio fue de 5 oC. Si en la unión de los rieles, cuya longitud es de 11.9 m, se deja un espacio de 5 mm, ¿cuál es la temperatura más alta que puede ser tolerada antes de introducir tensiones al material?
