A steel bar is held by two fixed supports as shown in the figure and is subjected to an increase of temperature ΔT = 100°C. If the coefficient of thermal expansion and Young’s modulus of elasticity of steel are 11 × 10^-6 / ⁰C and 200 GPa, respectively, the magnitude of thermal stress (in MPa) induced in the bar is ________
