A rod has a cross-sectional area of 0.001615 m2. When the rod's temperature is 12.23°C, it is placed among two rigid walls that are exactly as far apart as the length of the rod. The rod's temperature then increases to 27.23°C, and the rod exert a force of 5.334×104 N on each wall. If Young's modulus for the material of which the rod is made is 1.05×1011 N/m2, what is the coefficient of linear expansion of the rod?
