A steel bar of 2 m length is fixed at both ends at 20°C. The coefficient of thermal expansion is 11 x 10^-6/°C and the modulus of elasticity is 2 x 10^6 kg/cm^2. If the temperature is changed to 18°C, then the bar will experience a stress of A. 22 kg/cm^2 (tensile) B. 22 kg/cm^2 (compressive) C. 44 kg/cm^2 (compressive) D. 44 kg/cm^2 (tensile)

A metal bar at $21.0^{\circ} \mathrm{C}$ is $2.6000 \mathrm{~m}$ long. If the bar is heated to $93.0^{\circ} \mathrm{C}$, its change in length is $3.40 \mathrm{~mm} .$ What is the coefficient of linear expansion of the bar?
