A square titanium tube AB is rigidly connected to a circular steel bar BC at B. That steel tube BC is heated from 50 degree F to 1, 600 degree F. Assume the modulus of elasticity for steel remains constant with changes in temperature. Determine the displacement at B and the maximum normal stress in both materials due to the axial load applied at B.
