Determine the stresses, strains and final length of each bars due to uniform temperature rise of 40 degree celcius. Bar 1 has diameter of 16 mm and bar 2 has diameter of 25mm. Both bars have young’s modulus of elasticity of 2.1x105 N/mm2 but coefficient of thermal expansion of bar 1 is 1.4x10-5 /oC where as coefficient of thermal expansion of bar 2 is 0.2x10-4 /oC.
