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/°C and 200 GPa, respectively, the magnitude of thermal stress (in MPa) induced in the bar is _________
