Question

composite bar is made up by connecting a steel member and a copper member rigidly fixed at their ends
The cross-sectional area of steel member is A cm2 while that of the copper member is 2A cm2
for half the
length and A cm2 for the other half of the length. the coefficient of expansion of steel and copper are α and
1.25α respectively while the elastic moduli are e and 0.5E respectively. Estimate the stress induced in
members due to temperature rise of T degrees. (Ans 0.1 E α T in both members).
