Question
Two cylindrical bars, one of steel (E = 200 GPa, α = 11.7 x 10-6 m/mo
C) and the other brass (E = 105
GPa, α = 20.9 x 10-6 m/mo
C), are joined at C. The
end A of the composite bar is fixed, while that there is a gap of 0.12 mm between the end E and the vertical wall. the temperature of the Composite bar rises by 80 °C Find: The normal stresses in AC and CE, and the deformation of the
AC section. Answer: 101.35MPa©, 180.17MPa©,
0.152mm.
