![Figure Q1-Stepped Bar Axial Loading
A rod and tube of cross-section shown in figure
are firmly attached at their ends to form a compound bar. (a)
Determine the stress in the rod and in the tube when the
temperature of the bar is raised by 35°C. (b) What is the
magnitude and direction of the external force required to make
stress in rod equals to zero.
For rod, E= 190 GN/m² with a
For tube, E= 80 GN/m² with a =
